Well, my first advice would be to talk to Belial. He posts on the training board a lot. He's only an undergrad (Duke), but he's a genius and is majoring in the field. Very dedicated. Unbelievable.
My ideas:
With the recent spate of deaths (Corey Stringer the only name that comes to mind, but there have been others), the pressure on these guys. Lack of safety concerns in training, etc. (Mcguire taking andro, etc.)
Race. There was an article about a year ago in Esquire about racial issues in sports. Fantastic! And then "Real Sports" with Bryant Gumble had a segment on white basketball players. Interesting....
