I can say with a 100% certainty that Joker Phillips is worse than Dooley. 40-0 to Vandy? Don't care what "lack of talent" issues you have. I have a feeling I have watched a little more UK football games and pressers than you have also to form this opinion.
If any other coach had the talent we had then they would win more games. Hard to win when the defense allows teams to score every time they get the ball.
There's no way you can say he's the worst on any level. It's debatable as to whether he's the worst in the SEC, and it's highly unlikely that he's the worst in all of college football. To say he's the worst coach in America on any level is crazy.
Dooley has coached and/or recruited probably 80 different DBs since he's been here and they've all played like ass (that is, the ones who actually got into school at UT in the first place).
