The grass being slower at Wimbledon than in the past certainly helped Nadal. Some of his amazing saves would have been winners for Federer without it and in a match that close, it wouldn't have taken too many to change the outcome.

And, while I hope it was written tongue-in-cheek, Nadal's awesome biceps do nothing to give him power. You don't need huge arms to hammer a tennis ball, which explains why Federer with his stick arms can have a harder serve than Nadal.

While I agree that form is more important when determining how hard you can hit, "power" is without a doubt a factor. But you don't have to be the strongest guy to be the hardest hitter. The same reason the hardest hitters in boxing are not the "strongest" guys. They have more power and better form.

If it was only form and nothing else then the women would be hitting as hard as the men, and they don't.
