Perhaps if Michigan hadn't run through us like bad burrito through my colon after a night of heavy drinking this wouldn't be such a concern.....
While that stings, I don't think it is a factor in this. It would be a factor in UF btching about it, perhaps. But the SEC as a whole doesn't care who beat UF in the most recent bowl game.
If it were North Dakota State looking to hold a 'Spring Break' practice at IMG, I believe it would still be causing a stir of headlines. That Michigan, and Harbaugh in particular, are the ones leading the effort, only makes it louder and more visible. But the precedent being set is the point. As mentioned, Alabama and a lot of other places are dying to hold practices in Florida to help their recruiting. Conferences aren't aligned on rules governing this (SEC has to stay in-state, B10 doesn't, PAC12 and B12 and ACC rules are ...???).
If allowed, and I could see that happening if the Power5 separate further from the nCAA and make their own rules, it will create a wider gap between the haves and have nots. Even within the Power5, schools with the larger budgets that can support these activities will get better recruiting classes as opposed to programs like Vandy or Minnesota. It makes money an even bigger factor in shaping the landscape of football.
What would be interesting is if this would generate the attention if it weren't being discussed in Florida. I think the 'precedent' argument would remain up front for any fertile recruiting state like FL, GA, TX, Cali, etc. But if a D1 school like MN were to try and pull this - put it in WISC, you'd have WISC pitching a fit but nobody else would care. If MN tried to hold it in Idaho, Boise would have a fit....maybe...but nobody else would care.
