Think for the draw overall, given that there's just been this Olympics, a bigger deal than in years past, a lot of the top players won't be into it mentally. Guessing at a Isner / Nishikori final (a couple of guys used to heat and humidity, for one, and who have form enough to get to the Olympic quarters but are a bit fresher for not playing rounds past that). Won't be that surprised if Raonic takes out Murray too, though Andy could possibly not have a let down and instead ride his momentum (my guess is he won't though). This year, guys will only start to gear up at Cincy / play into the Open in the first couple rounds there.
i dont know. I think that andy might actually be fueled by his olympic win. He finally won a big final and over federer in straight sets. I think its possible he'll pull out but we'll see
