Even though Boston University is Hockey East’s only current lock for the NCAA tournament, they’re sure to get at least two entrants. That suggests that the only scenarios that knock Boston College out involve at least one Hockey East team other than BU making it (Mass.-Lowell, Vermont, Providence, or New Hampshire).
Hockey East is actually most likely to send 3-4, with 5 still possible.
The Big Ten is only guaranteed to place its conference tournament champion in the NCAA tournament. But, if Minnesota does well but fails to win the championship, the Big Ten could end up sending both the Gophers and the champ.
The NCHC is guaranteed to send five teams (Denver, Miami, Minnesota-Duluth, North Dakota, and Omaha), but is most likely to send a sixth (adding St. Cloud St).
The ECAC is only guaranteed to send its conference tournament champion, though its likely to send a second from Colgate, Harvard, Quinnipiac, or Yale. Harvard, Colgate, and Yale are all reasonably long shots, so not all can make it resulting in a maximum of three participants from the ECAC.
Atlantic Hockey will only send its tournament champion to the NCAA tournament.
The WCHA is guaranteed to send two teams, Michigan Tech and Minnesota State. They’re quite likely to send three and possibly even four from those two plus Bowling Green and Ferris State.
