The local beat reporter in Colorado Springs has tweeted that Michigan will fill in one of its holes in the 2012 schedule with Air Force. That's a one-off at Michigan Stadium, obviously, and a higher-quality one than usual. Given the way these things go Michigan is probably going to be shelling out a cool million bucks to the Falcons.
Why? Well, that year's home schedule is awful—OSU, Nebraska, and Notre Dame are all on the road with Alabama in Dallas—and whatever small cachet Air Force brings to the schedule it's better than Eastern Michigan or Baby Seal U. I'd expect the last nonconference opponent to be a MAC team.
