I wouldn't call myself a "Murray disciple" either, but I would like to see him breakthrough since he is certainly capable of doing it. It would make a great story, but to be honest, I would be happy if any of the top 4 won the title. If Djokovic wins, it would extend and cement his historic run as one of the most dominating in the history of the sport (IMO more impressive than McEnroe's run in 1984 because of how physical the sport is at the moment). If Nadal wins, he rebalances the scale of power and makes his rivalry with Djokovic more intriguing. If Federer wins, he once again shows his quality and proves to the world that even at his age he can still dominate the field, adding to his legacy. If Murray wins, the trio may become a quadri, and then who knows what will happen?!
I actually think it would be pretty darn cool if Tsonga or Fish could catch some breaks, make a great run, and win the title. I don't like Berdych's game very much, and I don't think Ferrer has slam-winning talent (sorry CC, I do admire Ferrer's game though and his physical stamina and mental fortitude) or that Del Po is back to his slam-winning form (though he may make a strong run).
Rafa has been struggling lately (his match with Verdasco in Cincy and then losing to Fish demonstrate this), but he may benefit from the easiest quadrant of the draw. My beloved Murray I think is in the toughest, most loaded quadrant; every match he faces may be a tough test. Djokovic's shoulder will be fine, and he should make it through with relatively minor resistance (at least until the quarters). Federer should be able to cruise also with relatively minor resistance (though he may face Tsonga yet again in the quarters). But you never know what is going to happen!
