I recently talked to guy that played OL for Florida during the transition when Dan Mullen left. He gave me some inside knowledge. In order to keep an amazing OL coach on staff, Urban promoted Addazio to OC. After winning a national title, the 09 team beat the hell out of bad teams, then struggled to score against better teams only able to win due to defense, and eventually lost to Bama to end the season. They were technically still in it as undefeated but it was similar to last year where we were just waiting for the die to roll snake eyes. Then in '10 they couldn't score on any team that had a semblance of a defense. We haven't gone down that far in 2 years, and I can't imagine '16 for us ending the same as the '10 season did at Florida, but I remember how bad it was I was in Gainesville those two years. Addazio just had an offensive philosophy that was pro-style and run-based. Whereas Urban was spread and speed. The different philosphy didn't matter so much when Addazio was just an OL coach. Addazio would would have been great as an OC in a pro style system, and when he moved on to HC at Boston College he was immediately successful calling the type of offense that he preferred to run (though it now appears to be going downhill). I just don't think Warinner fits as an OC under Urban's system, but think he could have similar success if he was playing under a pro style HC or was a HC.
