I would say that Berdych is more of a threat than Querrey.
I think Andy's draw is quite good better that Djokovic and for once Federer.
Andy is always a bit shakey in the first round but will see off Haase, then I don't foresee a problem until Quarters with Del Potro.
Federer has Tomic in the 3rd round. Tomic has just got into an ATP tour final, and just beat Djokovic in the Hopeman Cup. Then there is Raonic, and if he gets past him he could have Tsonga who has knocked him out of GS before.
You might be right about Berdych being the better threat. Querrey just lost a match yesterday and AO starts just next week, so he might not be a very good proposition at this point. Of course Berdych is a far better player than Querrey in terms of consistency, but I think Querrey is not as intimated by Nole. Berdych tends to get all mental against Nole at times and that’s worrisome. I am glad actually that Querrey lost yesterday because this should give him enough time to recover for the AO. Would be nice if Nole faces both to be honest and there’s a possibility of that happening as well.
