Can we play Guess Who? as to who said that about Dooley? I'll concentrate on the other SEC coaches since they're in the best position to make a statement like that.
Muschamp and Dooley are friends, so probably not him. Dooley was a Saban lackey, so probably not him. Richt is a Godly man, so surely he wouldn't say anything like that about someone else (would he?). Spurrier and Miles don't strike me as the type of guys to use the word "Dude." Could be wrong though. Stoops got to UK after Dooley so he didn't really have any interactions with him. Same with Mason at Vandy. So my money it's one out of the following: Pinkel, Gus, Bielema, Mullen or Freeze. I'm leaning towards Bielema, Mullen or Freeze. Who you got?
