If you ain't cheating, you ain't trying.
When star players can get $60+ million contracts, and journeymen types can snag MLE deals worth $30m or more, the incentive is certainly there to use PEDs.
I'm totally convinced that LeBron used HGH, just as I'm convinced that Michael Jordan, who was skinny with a full head of hair when he won a gold medal in 1984, and muscular and bald four years later, used steroids. He came out of a college rife with steroid users, especially in the football program, in an era when college athletic departments were chemistry labs.
The "OTC supplement" excuse for guys who get caught doesn't was with me either. Since Rashard Lewis got caught, his career nosedived.
I don't care if pro athletes use PEDs. I like to watch sports and athletes who can perform at the highest level possible. I do care if they use them and lie about it. Baseball was a better game when over-muscled comic book characters were slamming home runs at a wild pace.
