Shocking draw for Federer. All the guys who've been winning titles this season PLUS an impossible to beat Nadal in the semi
Rafa has the best draw and if Murray stretches Nole in the semi then he has a good chance of going one better than the Australian Open final.
Considering the 5 set slog at AO, with Nole bouncing back, there is no way that Murray taking Nole to 3 sets could weaken him enough to really effect his performance against Nadal. Nadal's best bet is if Murray beats Nole and has another inexplicable drop off in form, like he did against Fed in Dubai. I of course hope otherwise, that Murray can win it, but I think if Nole is good enough to beat Murray he isn't losing to Nadal in the final, no matter how tired he might be, simply because it hasn't mattered in the last 7 matches.
