Good draw for Fed, but in all fairness, there couldn't be a difficult group for him with the players present. Djoko on his side would've made it more difficult but even then he would've at least finished 2-1. The players that would make it difficult for Fed are Nalbandian and Murray.
In any case, Fed will likely have to face Djoko and Nadal back-to-back in the SF's and F's. He could theoretically beat the #2, #3, #4, and #5 players in the world and nobody will make a big deal of it because it's EXPECTED of him. It's difficult being the Expected Winner.
Nothing much to gain, a lot to lose everytime you toe up to the service line which is what causes a lot of his grumpiness on court.
