First of all, we all know College Success ≠ NFL Success, but just having that NFL experience is invaluable (See Saban, Petrino, Spurrier).
His 1997 Oregon team broke school records for offensive production. Put Boise on the map, as mentioned. His 2005 Offense at Arizona State was 2nd in the nation.
When he had a decent QB in his first year in Jacksonville, he improved their offense from 10th in the league to 7th. This year he's working with a rookie QB and no WRs.
Uh...what? The invaluable experience of losing?
Saban 15 - 17 (2 years then bolted)
Spurrier 12 - 20 (2 years then bolted)
Petrino 3 - 10 (Only stayed for 13 games...then bolted)
After watching a few Jag's games this year, they suck because of their offense, not their defense. Makes me uneasy. Just saying.
