fed said in his interview yesterday that djokovic played like he had nothing to lose, that is freely while fed was no longer young and could not play like that anymore thus implied that he played with more pressure that is tighter. i feel that fed recently has played tighter except for his win this year at the AO and wimbledon. he played tight at the french the past two years, at last years wimbledon, and now with djokovic. to define federer's tightness, he isn't as aggressive, looks like he has less energy, he'll mistime and shank a lot of balls, and not swing as freely. i think federer will rebound because he's such a champ but last year was probably his peak. i dont think he'll be as dominant these past few years but still has quite a few more majors a year.
