Last year his schedule wasn't much different, the only difference is he played Gstaad after Wimbledon. Yet this year some people are like "OMG, Fed's taking five weeks off!"
as if it's a big shock or something. Seems to me he pulled out of this tournament because he wouldn't have had any/enough practice time, since he was told to rest his feet for 4 weeks. So no doubt he's using the extra week to work with Tony, especially since Tony isn't coming to the US with him.
