Re: What does federer need to work on before AO 2012 to maximize slam chance?
Nothing, Federer's done. Therefore pointless poll since the option "nothing" is not there.
Lets see the other options though:
-movement/reflexes - Not possible as you grow slower and more passive the older you get
-endurance - same as above
-mental focus. That would have been interesting if he found a way to improve it. It's obvious over the years that he can't. Perhaps ease of pressure of not being favourite any more can give him more focus? Debatable.
-Backhand - didn't improve over the years and it's not going to improve now, sadly
-Return of serve . That is related to awareness/reflexes, therefore it goes back to questions 1 and 2. it's also a talent, either you have it or you don't.
-Lose weight/gain muscle. It will mess up his game even if possible. Federer never relied upon that to beat opponents.
-Get rid of Annacone. And hire who? it's obvious that the change of coaches can do nothing for him at this stage, he's his own best coach.
-Get more aces on serve. How many more, is that even possible?
Bottom line: Federer can't improve.
