I think Safin finally got his act together this year because of Federer. He finally met his real challenge and that ignited the fire inside of him. Before Federer he probably was uninspired and thought he could beat anyone on tour without really applying himself. The mockery of the press couldn't inspire him, the agony of his fans couldn't inspire him but Federer did. That's probably why he hired Federer's coach. If Safin starts defeating Federer regularly he probably would go back to his own self and starts tanking matches again.
