Well it would have been nice for Andy to be put in the same group as Robredo, but that can't happen now since they're currently 5th and 6th.
I must be the only one here who does NOT want Andy to be drawn into the weaker group. He really needs the tough tests and tough opponents. It will be good for his mental health to beat the likes of Nadal/Ljubicic/Nalbandian here.
It'll also be good for MTF's mental health if he were to beat Federer but we won't go there just yet.
