I disagree. Dooley was the only coach after the Fulmer years who built at least one elite unit while he was at UT. Our offense during his last year was definitely elite - I think statistically one of the best we ever had. Chaney and Pittman were hugely important for that success, but I give Dooley a lot of credit for keeping Chaney after Kiffin left. It would be nice if whoever we hire now is smart enough to keep both Chaney and Steele - it would give that new coach a head start because it should reduce the number of players (we have some talent and Pruitt should be getting some credit for that) getting into transfer portal. I'm assuming Steele has been building some relationships with the players by now as well, and also our players know he has been very successful DC at Auburn.
Having said all this, I would be happy if we bring either Kiffin or Dooley back. Butch was the only terrible hire as far as I'm concerned (just because these guys did not work out does not mean they were not logical hires at that time - there are no guarantees any hires will work out especially when you play against SEC competition).
