Nadal is 27 not 67. He had 7 months off to get healthy. His health did improve significantly. He has a chronic condition - that seems to respond well to rest. His play didn't come out of thin air.....he has been a top player since 2005. He is more muscular than most players - but not extremely so - well within the range of normal genetic variation.
Goodness. Normally confidence of ones position comes from having a strong case. But since you have no evidence whatsoever, I wonder where you get your confidence from. Again, I am primarily a Federer fan. I have no bias towards Nadal. What I do have a strong bias towards is, before people make slurs as bad a saying someone is using drugs - they have solid, hard evidence for doing so. Otherwise focus on tennis.
Your first paragraph is largely off point and mostly irrelevant. Your second is moralizing stemming from having built a straw man.
I have not said that X is using drugs. Kindly pay closer attention and get the facts straight. I have said that I strongly suspect that Nadal is using PEDs. More specifically, I suspect he may be using EPO at the very least. If true, I also suspect that he may be using others that facilitate recovery -- but to me, they're not nearly as obvious.
Nadal is primarily a retriever and grinder. His game has largely been predicated upon running down what would otherwise be winners and getting them back deep with topspin. His game is therefore dependent upon running and scrambling, the most physically taxing form of tennis. His game is therefore dependent upon endurance -- the reason he chronically stalls between points so that his muscles are completely replenished with oxygen. Yet almost miraculously he does not have an endurance athlete's build. He resembles -- more than any other player on the men's tour -- one of the power hitters in baseball during the 90s. And he shouldn't, because the taxing nature of his game should cause the catabolization of his muscles and render him as thin and gaunt as Djoker.
Furthermore I believe it safe to say that over the last five months or so he has not exhibited any signs of fatigue and does not appear to require any recovery time after marathon matches. I do not believe this to be possible without PED use. I also see no signs whatsoever of this "chronic condition" -- the one that caused him to miss 8 months -- flaring up at all. Given that he has gone deep in almost every single tournament he has played since March, this is very odd.
In fact, this should not be the case, at all. A physical drop off should be expected, especially after playing nearly every day for the past two weeks on the allegedly most harmful surface to his body. Instead, there has been no drop off in performance or any signs of fatigue. That would certainly be consistent with an athlete doping.
His beyond miraculous return makes it even more suspicious, in my view. Whenever any other top tennis player has taken more than six months off they have taken a full year to completely come back -- usually a combination of physical conditioning, technical rust, and a lack of "match fitness" or psychological reclimatization. This was the case with Muster, McEnroe, Delpo, etc. But not for Nads, apparently. Instead, Nadal was bagelling the #4 player in the world in his third tournament back -- just a few weeks after his return. I therefore do not believe he was injured to the extent he claimed, which leads me to wonder whether something else was occuring during his prolonged absence from tennis.
If Armstrong, Fuentes, the track star admissions, and Biogenesis have taught us anything, it's that if an athlete's performance seems too good to be true, it probably is. Had Nadal been on the tour fom June 2012 - March 2013 and shown gradual signs of improvement in his play over that time, that would be one thing. But to exit the sport for 3/4 of a year and show only small signs of rust while displaying beyond superhuman stamina and endurance when you reappear, I believe that should be regarded with suspicion by everyone since it seems too good to be true.
