Who said he only played tennis to develop his muscles? You do realise that taking steroids alone will not build muscle, you still need to lift weights as @Hitman will tell you...Isn't that exactly what I said above and the reason why Nadal couldn't have developed that sort of muscles only from playing tennis?
I'm not the only oneSounds like you are not the person to make that judgement.
Rubbish. He is moving just as well as he ever did, even after knee surgery...He isn't "running like a jack rabbit". In fact, he is demonstrably slower than even his prime years, which is why his FH side often remains vulnerable (he has problems moving to that side).
It's not hollow at all. He is 38 and running around like a 25 year old. At AO17 he played consecutive 5 set matches and showed no signs of slowing down.The argument is also quite hollow without some comparison. For example, I heard exactly the same argument, after he beat Nadal in the AO final, and your brethren couldn't stop implying what you now imply. Unfortunately for them, there was a statistic that showed that Federer has spend on the court a little over 13 hours vs a little over 18 for Nadal. Yeah, that put a stop on that BS.
