Realistically there's no one else that USF could get with a better resume'. The guy was the d-coordinator of an nfl dynasty, turned Miami around into one of the top teams in the nation, and turned North Carolina (a school with an absolute joke of a football team at the time) into a competitive ACC program that was nabbing top-tier recruits. Then you have all of the coaching connections this guy has throughout the nfl and college.
If you're USF and looking to go the young, up-start route, then of course Taggart is your man. But if you want to go the experienced route, then I don't know who even comes close to having the record that Davis has, and could recruit like this guy. And anyone who would exaggerate and say this guy comes with a ton of baggage would be mistaken. He inherited a recruiting scandal at Miami (much the way Golden recently did), and he was cleared at NC of having anything to do with recruiting violations.
Again, please show me someone with a better resume', that USF has a realistic shot at getting. Not out there.
