I honestly think that for the first time in like... forever, this one will be really wide open. I know, i know, many said this many times in the last couple years but really, you can argue that every single one of Roger, Djokovic, Nadal, Murray, and Del Potro has a solid chance.
Nadal will be rested, and of course we know what a beast he is at the majors, Djokovic is probably the best hard court player at the moment, Roger won Wimbledon, and he's very consistent in the last 12 months.
And of course Del Potro, a guy that probably has a game that when he's on, it's really hard to come up with anything if you face him. I'm really looking forward to this tournament, and if Roger can't win it, i'd love to see a Del Potro-Murray final.
