When he tries to play the stoic, like he did in US Open SF vs. Federer, after being inhibited by the crowd from the Roddick match, he is nothing. He must show emotions, he must turn it into the Djokovic show. the crowd loves it when he does his thing, the total intensity, like the head nods, the fist pumps, pointing to himself with #1 fingers, banging his chest and heart like King Kong, the eyes popping out of his head almost to the point of insanity, the strutting around the court with arrogance, the smiles, the roaring to the crowd and his box, Djokovic must lay his emotions on the line. When he acts like a machine he loses his passion, he loses that fifth gear. No tennis player in history can play a crowd like Djokovic who turned the US Open Ashe Stadium into a comedy show with his imitations with Michael Barkann. The crowd ate it up, they loved it, they love this character. and he feeds off it. it makes him stronger, it helps him play better, to own the crowd like that. No man in the hsitory of tennis has brought fun and laughter and comedy to the tennis court battlefield like Djokovic, he is an amazing special champion who has exceded the likes of Fed, Sampras, Laver, Macenroe, COnnors, with his magical ability to entertain on the court. Cesar Romero without the Joker makeup is unrecognizable. Djokovic without his playful attitude and intensity and freedom to let his emotions flow, is like a walking zombie of himself. I personally think he should do a Willy Wonka at this year's US Open, walk out to centre court for his first match with a very slow limp, then suddenly do a tumble somersault and show he was just faking the injury. The crowd would GO BANANAS. they would be in the palm of his hand. he would play incredible tennis. This spirit is the kind of spirit Djokovic needs to play his very best tennis.
