OK, I know this was discussed a couple years ago when SU announced their intentions of fielding a D-I Women's hockey team and all the rumors about a potential Men's team came up, but...
IMHO, There is no way SU is going to start a D-I program in any sport and join what is in essence a "mid-major" conference (although I understand that term has no true meaning in this case, but you get the point). An athletic department like SU would only join D-I hockey if it were to join a major conference like Hockey East, CCHA, or possibly ECAC. I doubt the AHA would even be a consideration for them unless it were to be used as a planned 2 to 4 year interim step to a major conference, which wouldn't be of much value to the AHA or its other members unless they were charged a higher membership fee for being a temporary member (which I imagine would be highly unlikely).
