I think that's what sports scientists are getting at. His performance is too good to be true. Like Lance Armstrong and Barry Bonds. At one point in Armstrong's career scientists analyzed his output during the TDF and more or less proved that it was impossible for a human being to generate that kind of wattage over a 3 week period.
With Lebron you just have to look at his physique, the changes in his forehead, and the ties he has to Miami drug labs, and it's all obvious.
My question is- why do Barry Bonds and Roger Clemens get punished and kept out of the HOF, and their careers are discounted as a fraud, when Lebron continues to be lauded as the best player in his sport? A ridiculous double standard.
