Jim Courier analyzed why American players have been failing to win Grand Slams since Andy Roddick triumphed in the 2003 US Open. The former world No. 1 believes Roger Federer, Rafael Nadal and Novak Djokovic were too strong. "The landscape is going to shit dramatically once the Big Three move along and I don't think that's probably four or five years away before the last of them will go.
Roger is 38 so it's fair to say that Novak and probably Rafa can still be doing at that age. There is even a younger generation of American players and then... Isner, Querrey, Johnson. A lot of players would have won Majors if they competed in another era.
So it's just been hard because they have been so darn greedy, so selfish." Courier added: "Roger had a period of time before he switched to the 97 inch racket where his forehand was a little bit off at times.
There were occasions where he gets under stress and sometimes he may pull up off of the ball and not drive through it. And I perfectly wish we were lucky enough to make this kind of mistakes compared to what he normally does.
We are really nitpicking with Roger because he had an incredible longevity, he is an amazing clean ball striker most of the time, but that just goes to show you that even the player who is almost perfect has imperfections at times."
