While I agree that is part of it, Flo is not unique in training pros. Coach Holloway and his staff at Florida (probably the best in the country the past several years) train a bunch of professionals and have several Olympic medals to show for it. Quincey Watts at USC and several other coaches around the country train as well.
At least as of a couple of years ago, what was a bit different for Flo was that he did not separate training the pros with his UT athletes. On one hand you can say that is good for the college athletes to train above them, but you can also point to it taking away from the college athlete coaching because the coach’s time is taken up with pros as well. Most coaches train their professionals in separate sessions (pros in the morning and college athletes in the afternoon).
No coach is everyone’s cup of tea and Flo runs things very much like a business, not a lot of sunshine. They rank athletes every week and it can be a very stressful environment. It would be more comfortable if it looked like what Florida has put together (even without as many National Championships). But it does work, and although Flo has not been as consistent as Florida, Arky, A&M, LSU, USC, and now UGA, he is certainly closer on the women’s side.
