You've got your tongue so far up Harbaugh's butt, it's likely to be lost.
Harbaugh won at San Diego. Not San Diego State. Not the Chargers. San Diego. As in almost-Division-II San Diego. Sorry, but I'm not impressed. Might as well count high school wins, while you are at it.
He had one good year at Stanford. One. You could look it up. And oh, he had a great quarterback that was waiting for him when he got there.
At Michigan, a place where he has absolutely everything at his disposal, he still hasn't finished higher than 3rd in his division. And he probably won't next year, either. A bit of bad luck, and he could easily finish 4th.
And you are dreaming if you think NFL GM's sit around and masturbate thinking about him. Everybody remembers what happened in SF when he left. They had a party. No matter what you or the media thinks, it was a shit-show when he left SF, and teams are not lining up for him. The media thinks they are, perhaps. The same media that once again puts Michigan in the top ten every year in the preseason.
So far, the man is all hype. He wins the spring, as they say. So far he hasn't come close at Michigan to winning the Fall. But if you want to lick his statue, have at it.
