Agassi reached a point where he knew his tactics had to match his skills so he changed his approach to the game and began to dictate as opposed to simply power through the ball. When he did this his confidence went up and he challenged Sampras with some of the best matches of their careers (albeit Pete usually came out on top) and his GS total obviously went up. The point is: does Roddick have the game and the ability to utilize new tactics? I disagree with him trying to come into the net as often as he does, he's not comfortable up there and he doesn't have the approach shots to do it. His backhand becomes a liability at times, especially on the run. I think if he learned to control the court more and lessen his need to run this weakness wouldn't be exploited as much. He just doesn't have Hewitt-like footspeed or footwork to play extended rallies where he's not in control of the point. There's no question he's talented but is he applying it to his game correctly?
