Lance Armstrong... greatest doper there was or ever will be

all this talk of dopinbg in other sports

is there any other sport where the athletes put themselves through as much effort and all out exhaustion as cycling
the effects of drugs in cycling is much more than in gold / tennis soccerball

obviously it will assist athletes in their training and give them an edge but i don't think any tennis player puts in as much effort in a year as the winner of the tour de spain put in on that tour alone this year

A doped and talented athlete will beat a talented athlete.Given the depth of talent at the elite level in men's tennis, it is pretty clear that physical and mental fitness determines who wins.
