You could argue the turning point of the 2012 U.S. Open—which starts today—already happened. Well, three turning points, actually.
1. Rafael Nadal withdraws with a knee injury. People who follow tennis will tell you they've seen this coming since before Nadal wore sleeves. He plays too hard to hold up for two weeks on the hard courts of Queens, year after grueling year. The day Nadal announced his withdrawal via—what else?—Twitter, Patrick McEnroe, one of ESPN's 47 tennis analysts, explained to the SportsCenter audience that Nadal plays tennis like an NFL running back. Like a Spanish Reggie Bush. A Majorcan Rashard Mendenhall. (Don't take Nadal early in your fantasy football draft, is what we're saying.)
