For anyone who doesn't think Federer has improved as a player, watch this video: http://www.youtube.com/watch?v=aQwe2WPK6qk The 2004 Federer top spin backhand is, quite frankly, the worst top spin backhand I've ever seen out of a Top 100 ATP player. Look at that thing...absolutely embarrassing. Luckily for Federer, his foot speed and forehand were at their most lethal to make up for it. Federer's backhand is still a very lousy shot, but he has improved it by leaps and bounds from back then. This thing makes Feliciano Lopez blush.
