Would it benefit Federer to let out some of his hot-headedness and play with a bit more emotion? Obviously, what initially pushed him (and others, i.e. Djokovic) into dominance was his ability to maintain a constant level as opposed to great up and down swings. It just seems as of late, that fire is what is keeping him from coming up with the mental goods to close out the big matches on the big stages. I'm not saying he should revert to his old racquet breaking self, but I wonder if he has just gotten too stable (if there is such a thing) in his on court mentality. There is endless debate on what he needs to do to beat certain players and I'm not trying to make a statement, just raising topic for discussion. Without a DOUBT Fed still has the physical ability. He has unfortunately come into a mental funk that needs to be fixed.
