As weak as the MAC will be this season, I wouldn't be surprised that the Zips have a winning season.
I'm curious, other than the number of good players graduating, what lends you to think the MAC will be weak? I'm not saying you're wrong, but there are some teams that are probably going to be just as good as they were last year. Off the cuff, I'm thinking of Ball State, UB, Ohio, and Kent as being pretty good.
I guess what I'm saying is, just because known talent leaves or graduates doesn't mean to me that the MAC will be weak. I'm no expert on recruiting, so I can't speak to what everyone else has brought for 2017-18.
