What to watch for in PWR this weekend

Leave a reply

This article looks at the most interesting outcomes of games this weekend, with a focus on what PWR might look like next Monday. If you want a more general analysis of the remaining regular season and NCAA tournament likelihood, check out the article, NCAA tournament outlook as conferences enter final regular season weekend, and the table, Wins needed to likely end regular season at PWR rank.

Biggest upside potential

#20 Wisconsin, visiting the red hot #4 Gophers in Minneapolis, has an opportunity to surge. The Badgers could climb to the 9-11 range with a sweep (as high as 7 is realistic), but will likely just stay put if swept. Of course, in the long run staying put is not good enough for the Badgers who needs 3-4 wins in their final 6 games to climb to the bubble (see NCAA tournament outlook).

#18 Boston College has a similar opportunity facing #8 Mass.-Lowell for a home-and-home series. Sweeping would provide a broad range of possible outcomes, from #8-#15 quite possible. Getting swept would likely result in a modest decline to the 19-20 range.

Biggest downside potential

As past readers of these articles know, just as teams around #20 usually have the most upside potential, teams around #10 usually have the most potential to fall.

#10 Cornell faces the most downside potential, with ranks 15-21 possible if swept by Rensselaer and Union. Given that these are the last two games of the regular season for Cornell, that would put the Big Red firmly on the bubble.

#9 Providence faces a similar outlook, with ranks 15-20 possible with a pair of losses to Massachusetts.

All of #8 Mass.-Lowell, #11 Penn State, #12 St Cloud St, #13 Ohio St, and #14 North Dakota face similar chances of a slightly more modest plunge with a pair of losses. Only Mass.-Lowell’s regular season ends this weekend, so others would have some opportunity to recover.

Top seeds?

#1 Denver and #2 Minnesota-Duluth each look unlikely to leave the weekend outside of the 1-3 range, regardless of outcome, and one of the two is almost certain to come out #1. Denver doesn’t quite control its own destiny, as Minnesota-Duluth stands about a 10% chance of sneaking into #1 even if both sweep. Other teams fighting for spots in the top 4 this weekend are #3 Harvard, #4 Minnesota, #5 Western Michigan, and #6 Boston University.

Methodology

Forecasts include the results of games played through Tuesday of this week.

Each forecast is based on at least one million monte carlo simulations of the games in the described period. For each simulation, the PairWise Ranking (PWR) is calculated and the results tallied. The probabilities presented in the forecasts are the share of simulations in which a particular outcome occurred.

The outcome of each game in each simulation is determined by random draw, with the probability of victory for each team set by their relative KRACH ratings. So, if the simulation set included a contest between team A with KRACH 300 and team B with KRACH 100, team A will win the game in very close to 75% of the simulations. I don’t simulate ties or home ice advantage.

These teams should really try to win this weekend

Leave a reply

Need to win

These teams clearly need to win this weekend. A pair of losses could plummet any of them into the 20s and out of reach of an at-large bid.

#13 Minnesota-Duluth
#14 Michigan Tech
#15 Nebraska-Omaha
#16 Cornell
#17 Minnesota
#18 Penn St
#19 Northeastern
#20 Clarkson
#22 Rensselaer

On the flip side, a pair of wins could propel any of them onto the 11-13 bubble in preparation for next weekend. Even with a pair of wins, 13 is a bit of a longshot for Clarkson and Rensselaer, while Minnesota will struggle to hit 14.

Minnesota-Duluth is the team most likely to survive a sweep, as the Bulldogs face a huge range of possible outcomes if swept—from 14 to 22 being somewhat likely, though 16-20 is most likely. Where they fall in the range will be determined by how the other teams on the list above perform — the more that lose, the better for Minnesota-Duluth.

umd

Michigan Tech and Nebraska-Omaha seem most likely to fall to 15 or below if they don’t emerge from the weekend victorious, so would face an uphill battle to get an at-large bid with no additional games to play.

mtech

Cornell could land in the 13-14 range with a single win this weekend (though 15 is more likely), which would leave them alive but with no control.

cornell

Minnesota and Penn State would each have an additional shot to climb in the Big Ten tournament, even if swept this weekend. But, each would also be in a pretty deep hold without a win. Even with a sweep, Minnesota won’t climb much, with 15-18 the most likely outcome. The Gophers would need an additional conference tournament win to gain confidence in an at-large bid. Penn State fares a bit better with either a single win or a pair of wins, being able to climb to the top of the bubble with the latter.

minnesota

pennstate

Though Northeastern could climb to the 12-13 range with a pair of wins, 14-15 is much more likely. Clarkson and Rensselaer face a broad range of possible outcomes with a sweep, being able to reach 13-14, but with 15-18 more likely, and even 19-21 realistic. All three need to win, plan to win next weekend, and get some help from others.

Mathematically possible?

These teams are long shots for at-large bids. Even with a sweep this weekend it would take a lot of luck to come out ranked #15. A subsequent win and a loss in the conference tournament shouldn’t move either much, so it would take some PWR luck and some cutline luck to get in at-large. Better just plan to win the conference tournament.

Win the conference tournament

These teams could give their fans some false hope by cracking the teens with a pair of wins this weekend. Unfortunately, it’s pretty unlikely to climb from there to above the cutline with a win and a loss.

#27 Dartmouth

Other teams not yet mentioned don’t even seem likely to be able to crack the teens this weekend. It would take an extremely unusual confluence of events for any of them to move into position for an at-large bid.

Six teams have an opportunity to dramatically increase NCAA at-large odds this weekend

Leave a reply

Likely in—#7 Yale, #8 Michigan, #9 Boston University, #10 Notre Dame

These teams are in good shape and likely to get an at-large bid if they win more than they lose in the coming two weekends.

If swept this weekend, their worst likely outcomes are falling to the 11-12 range, which would require keeping an eye out for potential additional downward movement and the cutlines (that is, how many of the at-large spots are taken away by autobids ranked lower than 16 in the PWR).

Of course, for Yale, Boston University, and Notre Dame, a pair of wins means another game. A loss in that game would probably result in giving back up some ground. But, that would still probably result in a safe position unless a lot of low ranked teams win their conference tournaments.

Note that Michigan’s position is slightly different because the Big Ten is still in regular season play. Even if swept by Penn State this weekend, the Wolverines would still have an additional game in the Big Ten tournament to either climb or fall. That worst possible outcome this weekend could drop Michigan as low as #12, from which another loss could push them out of position for an at-large bid.

Likely in if they win—#11 Harvard, #12 Mass.-Lowell

These teams would be in trouble if swept this weekend. Harvard’s likely fall could be to as low as 16, and Mass.-Lowell as low as 15. While it’s possible to climb a little bit while idle and have the cutline low enough to sneak into an at-large bid, it would be a bit of a longshot. I’ll also note that there are some extremely unlikely cases that could push these teams as low as 18 and 17 respectively if swept.

Sweeping, on the other hand, has the possibility of putting either in great shape — as high as 8 or 9 (though 9 to 11 more likely) with only 1 potential loss remaining.

One more team you should expect to see in the NCAA tournament

Leave a reply

The first five—Quinnipiac, St Cloud St, Boston College, North Dakota, and Providence

On Feb. 23, I called the top 5 “starting to look like locks” for the NCAA tournament (in order of their ranking at the time)—#2 Quinnipiac, #3 St Cloud St, #5 Boston College, #1 North Dakota, and #4 Providence. While those 5 have shuffled a bit amongst themselves, they obviously remain the top 5, and are even more certain locks.

None of them are likely to drop out of the top 7 in this weekend’s conference tournament play. Because a worst case scenario for any of those teams would also mean no more games before NCAA selection, there would be limited opportunity for additional downward movement.

Almost had it—Michigan

In that Feb. 23 article, I called (then #6) #8 Michigan too close and too many games remaining to call. The Wolverines have rewarded me for my caution, going 1-3, dropping two spots, and being at risk of hitting the bubble if they continue to lose.

michigan

The new “next one”—Denver

But what about the new #6 Denver (then #8)? They’ve been the hottest PWR team of 2016 with a 14-1-3 record since the New Year, including a 4-0 run since that article.

top10

The Pioneers are facing an elimination best-of-3 that is likely to result in no worse than a #8 PWR ranking, I’m comfortable saying you should expect to see Denver in the NCAA tournament.

Note, however, that Denver has not mathematically secured the bid. In very obscure scenarios, they could fall as low as 9 this weekend if swept (about a .1% of KRACH-weighted outcomes in which Denver goes 0-2). It’s conceivable, though incredibly unlikely, that the then idle Pioneers could slip enough further to fall below the cutline if almost all of the conference tournaments are won by teams outside the top 16. That scenario is extremely unlikely to still be in play after this weekend, but if it is, I’ll give full details of the likelihood and how it could happen.

This weekend’s big PWR movers

Leave a reply

Sorry for the lateness and any errors, had to crank this one out in a hurry…

More upside than you might expect

Not this week. Usually a team or two in the mid-20s have the opportunities for jumps approaching 10 spots. Plenty of teams in that range have the chance to jump about 5 spots, maybe even 6 if all goes well, but anything approaching a 10 spot jump from a team of any consequence is very unlikely.

More downside than you might expect

The high teens is a tough place to be this time of year.

#14 Penn State, idle last weekend but on the list of potential big drops two weeks ago, is in familiar territory — win 2 to stay in place, or be prepared to fall. A 10 spot drop to #24 is possible.

pennstate

#15 Minnesota-Duluth, which jumped 10 spots (as predicted) with an impressive pair of wins last weekend, doesn’t have much upside potential but stands to give back its ground if it doesn’t keep up its winning streak. An 11 spot drop to #26 is possible.

minnduluth

#16 Minnesota, which was also on last week’s potential big drop list, finds itself there again. Two wins won’t do much for the Gophers, but losses could result in up to a 9 spot drop to #25.

minnesota

#17 Michigan Tech, #18 Miami, and #20 Cornell also face potentially significant drops of up to 7-8 positions if they lose 2. They each, however, face more normal upside potential with success.

Weekend PWR watch — first conference tournament round

Leave a reply

Watching the top

#2 North Dakota used a pair of wins over #13 Nebraska-Omaha to climb past #3 St Cloud, which dropped a pair of games to desperate #15 Minnesota-Duluth. That leaves UND as the only team capable of taking over #1 from idle Quinnipiac this weekend.

und

In last week’s outlook I predicted that the top 12 were generally safe, with no one likely to drop below 14. Though there was some minor shuffling within the group, only Nebraska-Omaha fell out of the top 12, landing at #13 following a pair of losses to North Dakota.

top13

Safe this weekend

This week’s top 12 look similarly safe for another week, with no one likely to come out of the weekend below #13. Note that quite a few of these teams, including #9 Notre Dame, #11 Harvard, and #12 Mass.-Lowell, are insulated against much movement by being idle this weekend. Teams likely safe in the top 13 include:

#1 Quinnipiac
#2 North Dakota
#3 St Cloud St
#4 Providence
#5 Boston College
#6 Michigan
#7 Denver
#8 Yale
#9 Notre Dame
#10 Boston University
#11 Harvard
#12 Mass.-Lowell

Around the bubble

Most teams from #13 Nebraska-Omaha down to #21 Minnesota State could end up on either side of the bubble—at #14 or higher after this weekend, or below 14. The notable exceptions are #16 Minnesota will struggle to climb above #15 and idle #19 Robert Morris isn’t likely to climb beyond #17.

Need to climb

A handful of teams can’t quite make it into position for an at-large bid (which we’re currently calling #14 and better), but can come out of the weekend in the teens, preserving hope for an at-large bid with additional conference tournament success. Those include:
#16 Minnesota
#19 Robert Morris
#22 Northeastern
#23 Clarkson
#25 Rensselaer

Need to win their conference tournaments

Idle #24 St Lawrence, and #26 Bowling Green and below are unlikely to come out of the weekend in the teens, and thus face a steep climb to gain an at-large bid.

A couple data notes

The Eastern teams are already in conference tournaments, and thus playing best of three series this weekend. Their “win 2” curves include both the 2-0 and 2-1 scenarios. They are generally double-topped, and the 2-0 scenario is the better outcome.

There seems to be some confusion about whether the Feb. 20 Denver vs CC matchup was a neutral site game. As of now, USCHO, CHN, and the Denver site all list it as a home game for Denver; while collegehockeystats.net and the CC site list it is a neutral site game. This has a minor effect on RPI which does not affect any of the above outcomes; though these calculations assume it was a neutral site.

This weekend’s big PWR movers

Looking up!

As mentioned in yesterday’s PWR outlook article, all the teams from #20 St. Lawrence to #26 Clarkson have the potential to climb into the teens this weekend. But, #25 Minnesota-Duluth and #26 Clarkson, in particular, have the potential to make huge jumps.

The #25 Bulldogs could find themselves as high as #14, a jump of 11 spots, with a sweep of #2 St. Cloud St. Most likely with a sweep is a still unusual climb of 8-9 positions to #16-17.

duluth

#26 Clarkson could find itself as high as 16 with wins over Dartmouth and Harvard, though #19-21 are more likely. The likely outcomes for Clarkson with two wins cover a surprising #16-#23 span. Clarkson’s outcome with two wins would rest a lot on other games, with the Golden Knights cheering for sweeps from Alaska Anchorage over Minnesota St, St. Cloud St over Minnesota-Duluth, Maine over Northeastern, Alaska over Michigan Tech, and Canisius over Robert Morris.

clarkson

Going down?

Every team in the #14-22 range, except idle #15 Penn State, could fall more than five positions with a pair of losses. #14 Cornell, #17 Miami, #18 Michigan Tech, and #16 Minnesota are facing particularly steep falls.

Cornell could see itself fall as low as #24 with losses to Rensselaer and Union, though the spread of likely outcomes stretches a huge span of 17-24.

cornell

Miami faces a steep drop to as low as #29 if swept by Colorado College, with a still significant drop to 26-27 most likely.

miami

Michigan Tech could find itself as low as #28 if they drop a pair to Alaska, though #24-26 are more likely.

mtech

If Minnesota gets swept by Michigan, it will face a broad range of potential outcomes that stretches as low as #25. #19-23 are all reasonably likely in that scenario.

This weekend’s big PWR movers

Leave a reply

As the weekend game results come in during the final few weeks of conference play, college hockey fans start watching the PairWise Rankings tables for big moves that might push teams into, or out of, position for an at-large bid. Here are the teams most likely to be cited on forums and in tweets this weekend for “surprisingly” large moves.

Don’t look down

#14 Penn State is unlikely to benefit much from a pair of wins over #40 Ohio State, but would likely plummet to about #20 (as low as #24 is realistically possible) if swept.

pennstate

Surprise! #15 St. Lawrence could climb just a little with a pair of wins over #10 Yale and #53 Brown, but is facing steep decline to the #22-24 range with a pair of losses (or a more modest decline with a single loss).

stlawrence

#17 Rensselaer won’t move much if they defeat #1 Quinnipiac and #55 Princeton, but face a steep decline of about 9 ranking positions if they drop both.

stlawrence

Going up?

#23 Minnesota Duluth, which I already noted is facing significant upside potential with a visit to #3 North Dakota, could surge to the #14-16 range if they hand the Fighting Hawks a second consecutive conference sweep. Even a single win would likely result in a noticeable climb.

duluth

#25 Robert Morris could excite fans with a likely move into the teens with a pair of wins over #30 Air Force. But remember, they’d need a repeat performance against Canisius next weekend to avoid giving that ground right back.

The mathematical long shots for at-large NCAA bids

Leave a reply

While #24 Minnesota St is pretty unlikely to climb to an at-large position by the end of the regular season, with a perfect run they could get close enough that an at-large bid wouldn’t be out of the question with some additional success in the conference tournament and a little luck.

The same is true, with decreasing likelihood with the lower ranks, down to about #29 Ferris St.

#24 Minnesota State
#25 Robert Morris
#26 Northeastern
#27 Bowling Green
#29 Ferris State

(Note that #28 Union getting into position for an at-large bid is particularly unlikely — that doesn’t mean mathematically impossible, it just didn’t come up enough in the simulations to be noticeable).

With two weeks until conference tournaments begin, teams on the bubble need to get hot

Leave a reply

Picking up where I left off yesterday, in A few top teams are starting to look like locks for the NCAA tournament, those teams currently ranked #10 and below in the PWR need to do some work to ensure being positioned for an NCAA tournament bid.

If #10 Yale and below lose more than they win, they risk going into conference tournaments in the teens and having to glue themselves to this blog. #11 Boston University and #12 Harvard have very similar outlooks to Yale, each with 4 scheduled regular season games remaining, and each wanting two wins to maintain their current position.

yale

#13 Mass.-Lowell can also maintain its current position, or slip slightly, with a pair of wins. But, that would leave them squarely on the bubble going into conference tournament play.

masslowell

Because the Big Ten regular season extends later into March, #14 Penn State has 6 games remaining. But, the Nittany Lions need 4 wins to make maintaining their #14 ranking the most likely outcome.

pennstate

#15 St. Lawrence has kept me in business this year, with a wild ride from #10 in my inaugural January article, down to as low as #27 at the end of January. I noted back in January that they would need to win about 9 of their last 10 to go into the conference tournament on the bubble. After a 5-0-1 run, the Saints are still positioned for a #13-14 ranking with no more losses, or a #15-16 ranking with one loss.

stlawrenceride

stlawrence

The #16 Minnesota Gophers have 6 games remaining, and most likely need 5 wins just to maintain that ranking going into the conference tournament.

That should be no surprise, as all the way back on January 6, I published a chart on Minnesota that suggested Minnesota needed to win about 12 of its remaining 16 to end up ranked #15-16. Including two additional tournament games, Minnesota has gone 8-4 over that period, leaving them little room for additional losses.

minnesota

#17 Rensselaer, #18 Cornell, #19 Michigan Tech, #20 Miami, #21 Dartmouth, and #22 Clarkson all need to win out to be most likely to end the regular season in the #13-14 range.

rpi

clarkson

#23 Minnesota-Duluth has a bit more wiggle room, with a finish in the #14-16 range likely with even just 4 wins in its remaining 6 games. The Bulldogs have the notable RPI improvement possibility, and challenge, of playing #2 St. Cloud and #3 North Dakota on the road.

In late January, I suggested that the Bulldogs would need to win 8/9 out of their final 11 to end up in the 14-16 range. In the interim, they’ve delivered a 3-2 performance, so it’s a modest upside surprise that they might be able to afford two more losses.
