Uhh what?
I have said it before but I will say it again. My opinion is the small condensed footprint is truly what is best for mid-major conferences and the current MAC has a pretty good thing going on continuity and regional rivalries. I have to assume the MAC is believing the lie that this will draw in and expand interest in the conference. No, it won't. But it will put a random annoying out of place opponent on everyone's schedule.
In my opinion, Buffalo was already that opponent and at least with the new “pod” structure in Football there are now two teams in the Northeast. UMass definitely boosts basketball too.
Buffalo is a step out, but not that bad. Same with NIU.
If it is just Umass, I hate it. If it is part of a bigger expansion as others have said, I could get on board. I just don't like having 1 random team that doesn't fit geographically and has zero history with anyone. Similar (but bigger) discussion to the 4 pacific teams joining the big 10. Together it isn't as dumb and crazy as if say they just added USC and no one else.
