Re: P.E.D and Roids in the NBA?
As a keen gym enthusiast and past amateur bodybuilding competitor, I can't truthfully believe that even with the best genetics and nutrition and training that an NBA team can provide. That Lebron James, Karl Malone and Ben Wallace aren't chemically enhanced.
Getting to that size alone is near impossible naturally, and would take the better part of a decade to reach such size and tone. But to have to do it while participating in so many games and cardiovascular training is impossible naturally. Couple this with the agility and speed that such players have an it's generally implausible for such progress to be made without artificial help.
I'm sure that many other of the players in the league use enhancers as well. I'm not all that aware of the NBA's drug testing policy but it was pretty heavily critcized recently.
