Why did Barry Bonds put his career in jeopardy by taking steroids? He was already a 30+ HR, 40+ Steal guy and on his way to being a Hall of Famer. Now he will never even sniff the HOF.
Fitness and strength was never a big thing on the PGA tour. Now a plethora of golfers have placed an increased emphasis on weight training, more so than ever before. You don't think it is possible that Tiger has started to usher in this type of training, and did so with a little extra help?
Again, I'm not saying he took them. I just think to deny the possibility of it is pretty asinine.
