Kev, you underestimate the effect that Muschamp had on the Gator program. It's like sending your kids to a a prep academy due to its prestige and come to find out the school was not only not accredited but was using the kids as drug smugglers and slave labor. It takes time to recover from that. Muschamp's only ability was to take a young player and squeeze every ounce of hope and talent out of their soul. (For the record, many here admired Muschamp's frothing death stare).
All this is in the psyche of the players, that's why Treon could not be rehabilitated. I think not only Mac's personality but his ability to allow and help the players to develop is just what this program needs. I really believe once he changes the culture and the team buys in, we will see critical mass in talent.
