Make that A LOT easier. Can't see too many players pushing Federer. Djokovic's play has been sporadic lately. Murray may have the best shot but he's got a ton of pressure on his shoulders.
That means if Fed wins it he regains the number 1 spot I believe. Also with Nadal out that means Murray becomes the number 2 seed. He has a good chance of making it to the finals w/o having to be on Fed's side of the draw. He just needs to make good on the later round matches.
