excellent to hear, too!! it shows he is committed to do well (or win) the us open, because to skip 3 tournaments that you won the previous year means you lose a lot of points, and we all know he has his eyes on the rankings.
one thought i had is that it would be good for him to play on the clay to get his confidence and rhythm back...you want to feel it in your bones that you can 'roll' in your matches, and after some frustrating weeks on grass, i doubt he really feels that way at the moment. you dont want to get in any habit of losing to people you can usually look in the eye and be able to commuincate "i am going to beat you"...that's always effective for the top players!
but its a good sign that he is figuring out that that.......perfect little body of his....needs some rest to be at 100% percent. i dont think he uses that body on-court only and he could strain a muscle.
so defending the titles (and the points) would be good for short term thinking, but long-term i think it is right, and it is mature. (both good signs!)
BUT...i dont know about the rest of you....but i dont believe what he says about now liking or loving grass. i mean, i'm sure he feels like he 'made friends' with the surface a little bit, which is great...but until he can fully play his own game on grass (which feels good, as NOT being able to play your game does NOT feel good), i dont think he loves it. i bet he thinks it sucks. but whats great, to me, is he is UP for the challenge and taking it on directly as he did! he will learn to love it!
