At this point, no to Jim Harbaugh. In his defense, his offensive recruiting is terrible in college and he is predictable with his offense, and we have had enough of that. Once I found out he hired Pep Hamilton for Michigan, that was enough for me.
Frank Reich, Josh McDaniels and Dave Toub should be the top 3, IMO.
The first 2 will instantly put our offense to be maximized, IMO. The last one would be fine as well if the first two decline, IMO.
