Is it his 4 years of dominance? nu uh Masters series wins? not quite Is it his 14 GS? no His career slam? nope but close It's his ability to attract people and cause peace...people who don't even watch Federer matches are in his threads, any and all threads generally become about him positive or negative. Everyone spends good amounts of time analyzing his words and style of dress. Most importantly, is that despite the 4 way rivalry within the top 4 (they all played each other AT LEAST once) all Murray, Djoker and Nadal fans can unify in an effort against him. I don't about you but if i have that many people exerting the energy it takes to hate me when they've never met me i'd say i was doing something.
