I've seen it countless times when Djokovic has gotten very angry and broken racket's etc. he seems to then play better. When he doesn't show this anger he seems to lose big matches e.g. Wimby 12' SF, USO 12' Final, Wimby 13' Final. But when that angers burst out of him e.g. USO 11' SF, Miami 15' Final, IW's 15' Final, He seems to find something extra and turn matches around. There seems to be a definite pattern appearing. Also if you go way back and look at USO 07' final, where he missed all those set points and still didn't show much anger. Then come AO 08' he seemed to have an air of anger about him as if its like he said 'its my time now move over', especially in the match against Roger in the Semis, very vocal and doing those long stares. It really does seem like anger plays a big part in Novak's game and when he loses that he tends to roll over more easily.
