Agreed (on attrition). There was a post several weeks ago stating that it is well know by the Michigan cognoscenti that several players would not be on the team next year. I won't speculate (under pain of Bolivia,) but it should become very clear once Spring practice begins. If you must speculate, all you really have to do is figure out who was injured prior to 2012 or during 2012, and had to sit out significant time. You can count on at least two of them receiving a medical waiver or the like. This should bring the number of spaces up to 18. You should expect another 2 - 4 unexpected departures, bringing the count up to 20 - 22. With back-dating, I thing the class can easily be 23 - 24.
I'VE HAD JUST ABOUT ENOUGH OF YOU SONNY
