He wasn't all that into the idea of taking the job two years ago ... but I get the distinct impression he's all in now. College football suits him. I feel like his 'routine,' if you want to call it that, has about a four-year shelf life. Beyond that, it wears thin. Four years, obviously, is how long a kid wiill be at Michigan.

In fact, what I would fear most if the Rams were somehow able to lure Harbaugh away from Michigan is that he would immediately regret leaving Ann Arbor.
