So these are the top 16 seeds, and I'm going to do my least favorite thing (other than surface discussion) and speculate on potential matches that will probably never materialize.
The seeds are interesting in that there is plenty of uncertainty. For instance, in most slams in the past few years, we generally had an idea about what would be better for the top 2 seeds as far as who lands in their quarter, half, etc... However, with Federer's form being so shaky, Murray's back being troublesome, and question marks about Del Potro at the AO, so much is unknown.
For example, is it better to have Ferrer or Murray in your half? Under normal circumstances, this would be a no-brainer. But given Murray's return from injury and unknown form, he might not make it to the semis to begin with, meaning it's actually better to get HIM. Of course, that is also dangerous because what if he plays well and gets there? If I'm Novak, I'd probably wouldn't want the risk and just hope for Ferrer. On this surface, he's a nightmare match-up for David and will beat him regardless. Meanwhile, Ferrer has given Nadal more trouble on hard courts than many are willing to admit.
The quarters are super interesting to me. Berdych's form has been iffy, and Federer doesn't seem to be playing well enough to pose a serious threat to Djokovic or Nadal. If I'm Rafa, I'd be hoping to avoid JMDP (even though Nadal would be favored on this surface). Federer remains Federer, but it's a huge ask for him to beat Nadal here, while the latter has historically dominated Wawrinka and Berdych. Novak would probably hope to avoid Wawrinka and Del Potro (though of course he'd be the favorite against everyone).
As far as 4th round opponents, there aren't too many daberous ones. There's Haas (though he doesn't have much of a shot against the top 2 on this surface, so I'm hoping he gets a decent draw as I'd like to see him do well). Tsonga's always dangerous, and nobody wants to play Isner, regardless of form or surface. Everyone else seems kinda meh, except maybe Raonic.
