A lot of people talk about Federer's superior game in his heyday and with good reason; but they overlook the fact that what made him successful was ultimately his ability to play well (use his tennis bag to its fullest so to speak) almost all the time, during a match and during an entire year.
Does Fed's expanded "tennis bag" include netting or hitting long (what were before)routine running FHs? Or struggling with journeymen in early Wimbledon rounds? How about losing matches when he's 2-0 love up? He could have certainly done without those new additions.
