Indeed Fed is playing great! His great run will ultimately end, when? I still don't know.. But to tell you the truth, I really though Nadal would beat Fed at IW and I got a really nice surprise when I saw the scoreboard... Miami? Well, I would think Fed has all the motivation to win Miami considering that if he does, that would mean he would be #2 again, so I believe that is a hell of a motivation. Can he accomplish it? who knows. Yeah, Roger is playing great, but you still got Djokovic, Nadal and even Murray to deal to win the title and that is a tough achievement that can be done but I don't think it will be easy..
