This is a pretty easy draw for Federer imo. Davydenko is well past it, Tomic is no threat to him, Fed will routine him like last year then it's either Raonic or Kholschrieber. Well either one of those 2 will lose most likely in 4 sets and then a potential qtr final against Tsonga who looks a little under done (maybe he'll pick up form) he didn't look too impressive today. The only really tough part is the semi final. Murray could prove to be very tough for Fed especially considering it's a SF and not final and Murray has confidence he can take 3 sets off Fed now. The final will most likely be against Novak where if he gets through Murray he'll most likely lose to Nole since he's never taken a set off Novak since AO went plexicushion.
It is easy compared to what really?
We analyse who could possibly be more dangerous than Davydenko in rd2?
I look beyond the 32 seeds and I find only Benneteau who is anywhere close to that dangerous, mostly because of matchup issues.
Who is more dangerous than Tomic to face in rd3? No one.
Who is more dangerous than Raonic in rd4? Specially considering that every match between them have been close, maybe Gilles Simon would be worse but that is the only one I could think of.
Who is more dangerous than Tsonga in QF? Only Berdych for Federer.
Muray is 10 times more dangerous than Ferrer.
So this is the most difficult draw you could give Federer if you handpicked his opponents, except changing Tsonga with Berdych. It is not an easy draw.
