It appears that the Alaska programs are at risk of shutting down regardless due to significant budget cuts. It sounds like UAH is going to try to keep its program, and Arizona State has proven that it is possible to get into the tournament as an independent.
I do think this is actually good for college hockey longer-term, though. The default assumption is that the WCHA defectors all stay together. If that's true, there's still room for it to grow. I know Oakland did a feasibility study to add hockey, and I think it would make a lot of sense because they're not a football school, they have a decent sized student body, and they'd have natural rivalries with the other Michigan schools in the league. I think there are other schools in the Great Lakes region that could be successful in adding D1 hockey as well (eg. Green Bay, Northern Illinois, Toledo)..... The alternative is to add the westernmost schools from the Northeast leagues (Robert Morris, Mercyhurst, Canisius, Niagara), which would then allow other schools in the Northeast to add hockey with a conference to go to. Apparently Navy is seriously considering going D1. Schools like Delaware, Drexel, Penn, Lehigh, Bucknell, Rhode Island, Central Connecticut, and NJIT could all be successful programs, as well..... Beyond that, there are also rumors of some schools out west, including UNLV, going D1.
