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.
This is so obvious and easy to see. I guess some people have been blinded by the "Roger always gets easy draw" propaganda. Of course Roger does sometimes get easy draws but he gets also as many tough draws. People are like a broken record.
It's not that we expect Roger to lose against Tomic or Raonic but that they are harder when compared to other possible players for that round. The chances of an upset although always small, when it comes to the big 4 in a slam, are higher when you face opponents like Roger will in this year's AO.
