Can't say Bohn is the problem. Hawk ended up being a disaster, but at the time of the hire he was a pretty coveted prize. And for the extension, we just went to a bowl game and were getting a top 20 recruiting class. On paper the hire and extension, at the time, made sense. And I remember both, particularly the hire, being pretty popular around these parts.
I don't think Embree was Bohn's first choice. I'm guessing the cheapness and 'recapture the glory days' boosters had a lot to do with that decision. Plus, with the state of the program, Bohn's credibility took a hit.
Overall, with the other coaches hired, PAC XII deal, the Chief Marketing Officer, innovative fan events etc, Bohn's done a pretty good job. B+ IMO.
Ways to fix the program from the admin side: free up admission exemptions for football players to make it easier to get guys in here, hire a top notch OC/DC from a perennial BCS power or a good HC from a smaller conference, and invest in facilities.
Finally, keep the boosters involved, but let's get past our past. It was great, but college football has changed and we need to change with it.
