Good - you guys can go discuss conspiracy theories at the next tinhat wearer's anonymous meeting. This thread is for those who live in the real world where it is understandable that athletes putting enormous strain on their body may get injured.
You are right. There is no need to think about conspiracy theories because there is not any proove of something wrong with Nadal's injury, as he has always talked about his injury during all the time that he has been away from courts. And his doctor, Angel Ruiz Cotorro, has described the injury of Rafael Nadal with details. And, for sure, for a player like Nadal (a man that is obssesed with being competitive and compete) missing the Olympics (where he was the spanish flag ambassor, something that was very emotional for him because of his patrioticism), the US OPEN (he trained to be on the US OPEN but he felt pain, in fact he was thinking about coming back in Winston-Salem), the ATP World Tour Finals (the only big trophy that Nadal hasn't win until today) and the Australian Open (he was not physically fine to go to a Grand Slam with guarantees of being competitive there) is something that, for sure, he doesn't like.
For me it hurts seeing Federer fans that are Nadal haters or Nadal fans that are Federer haters. In general I can't understand people that has always a hated player in his mind and that is always criticising the player that he dislikes rather than admire the player that he likes. I mean, for me tennis is an sport where this actitudes aren't welcome, it mixes better with football. Guys, we have an excellent generation of tennis player with different game styles. We have to enjoy them... in ten or twenty years I think that haters will appreciate this time and the players that they were hating before.
