This thread is hilarious on many levels. Not, because Federer is not a doper, but because out of the 10 players he is actually the least likely to dope. No point throwing mud, but I think we all know when we are seeing things that are unnatural. Marion Jones, Lance Armstrong, Barry Bonds etc. I think deep down everyone on this board knows the most likely players who dope.
Doping is a huge problem in sport. It is hard to say how bad it is, but lets be honest. Apart from cycling their is no real attempt to catch dopers. However, we need evidence.
As for this match Federer hardly did anything amazing. The points were not long and he held serve very easily. Federer was exhausted afterwards. Federer must have one of the best deciding 3rd set records in history and top 3 tie breaker record in history. His poor record in 5 sets is actually due to him getting tired.
