Nadal has done an excellent job since his return. For someone to be out that long and come back and make finals and win tournaments - IN THE MEN'S GAME!!!! -- he must be doing something right.
I noticed a pattern with a lot of Nadal fans. Seems like his fans are harder on him that non-Nadal fans! Glad you all are not Federer fans!
But at any rate. Nadal is still playing pretty good tennis right now so I don't count him out in any tournament (unlike some of his fans)
Roger's is the 'question mark' to me. I know he normally takes a lot of time off during the year, but he's getting older, and it seems like he needs some time to 'get back in the swing of things'. With him being the defending champion here -- he's going to have to get back in the groove in a hurry! He hasn't won a title this year yet (that's another streak going as well)....so I hope he can start here but with almost 2 months off - I honestly don't know how Roger will play this week.
Federer had a period where he looked relatively poor a few years back, early exits, shanks all over the place on the BH and the forehand was unreliable.
It got so bad that few ever thought he could be competitive for any decent length of time.
Fed showed that he had the will and desire of a champion to not only play good again but to rack up some masters, WTF, slam and a return to #1 while both Nadal and Djokovic were playing in their prime.
Nadal is at a serious crossroad, it's not the knees that will hold him back but his desire and will to win.
