I'd like Harbaugh to stay, but can understand another flirtation with the NFL and its appeal. I'm not holding him to his comments last year that it was a one-time thing. Maybe that's part of the reason Harbaugh likes the NFL. He can deal with football, not worry about all the other year-round stuff, and not feel he is tied somewhere for years because otherwise that is "unfair to his recruits" or that he owes the fanbase something.
8 years in, which is about as long as I expected him to stay when he was signed. In his 7 full seasons, had a 13-win, 12-win, three 10-wins, a 9-win and 8-win season. Again, about as good as I expected, maybe better. 2-5 vs. Ohio State, with a decisive home win and road win - again, OSU is a more elite program, 2-5 is to be expected. Going into 4 of the 7 OSU games, a Michigan win would have sent them to the playoffs (via the BIG championship game first). Back to back B1G championships. Would have been nice to have at least made it to this year's championship game, but may not be a burning desire for him compared to a Super Bowl ring.
