The list of the "Best" college coaches is, imho, Coach K, Bill Self, Tom Izzo, Roy Williams, Rick Pitino, John Calipari, and Billy Donovan. I think they are the "best". Now we all know that none of them are leaving their current jobs for UT.
Then we could go great coaches, who MIGHT be better hires than CBP. In no order, Tom Crean, Jamie Dixon, Gregg Marshall, Fred Hoiberg, Buzz Williams, Shaka smart, Brad Stevens, John Beilein, Thad Matta. Again, I don't see any of these guys leaving their jobs for UT, in fact, allegedly, a few of them turned UT down last time.
Then I think we have CBP. He is a proven commodity.
After him, I keep reading guys like Lawrence Frank, Rick Byrd, Mick Cronin, Richard Pitino...etc. I believe that CBP is the "best" available. Not saying that others shouldn't get a look. But, CBP will end up coaching somewhere, and I'd hate for our next hire to be another flop, when CBP could have been hired.
Again just my opinion, I'm by far more in tune with football. Most of my BBall knowledge is gained from reading various forums and articles.
