OK a few quick things:
1) If you're underwhelmed by the Fedal "rivalry," base your arguments on their matches up until a couple of years ago. This is soon to be 32 year old Federer playing Nadal (who happened to be having a good day too) on clay. What did you expect? Sure, Roger's performance was especially bad, but to use these matches as some sort of tell-tale sign as to how overrated this rivalry is seems silly.
(Cali is excluded from this paragraph, since he thinks Roger is still as good as ever, 31 year old is still almost someone's prime, and Roger can just flip a switch the moment he chooses to. Apparently he chose not to in this match).
2) There's little to take from Fedal matches these days, especially on clay, but I actually think Nadal has re-adapted himself to Roger's old-age acquired weaknesses, such as stretching him on his forehand side. Back in say, 2006-2007 (or even 2008 for that matter), going after Roger's forehand was suicidal. He's not as fast moving to that side these days, and Rafa is consistently exposing it with his CC backhand (I first noticed it at RG in 2011). As if this match-up needed to become even more complicated for Fed.
3) The good news for Federer is that he can't possibly play this bad on grass. I think he'll be surprising people there, again.
not that he can win with two handed backhand but atleast it doesn't look as ugly.
