Harbaugh is a great coach. He will do well at Michigan.
I expect that Harbaugh does best when he feels in control of the situation. He was not a great fit as a Bears QB, but diid a lot better with a different coaching staff at Indy. (I’m a lifelong Bears fan, sorry to say).
College football is a perfect fit for this guy. I expect Michigan to return to its former glory days. The competition has greatly improved since the 1970’s. My beloved Illini will never compete, but look out for Wisconsin, Iowa, and their old foes at OSU.
