whatever (if) he was using, it didn't really work out. I assume if you were doping you would win something, get your rankings up ...
Dude has got the game to be a SOLID top tenner/slam contender.
Resorting to any sort of doping is a cope out in my opinion.
More commitment to excellence.
These are but a few avenues that could yield dramatic results for a player who has yet to realize their true potential.
Witness Andy (not Roddick).
He is starting to put the pieces together and
he's not done yet.
Plenty of room for improvement in his game without resorting to short cuts.
