playing doubles recently now makes sense in hindsight. It was part of
a grand strategy to become an all-court-player. I think that he has
arrived. Reminder: Fed took the same route along with a racket change
as he lost a step to age. This is also the path of Ken Rosewall who
was a dominant back court player who used it to stay competitive into
his late 30s. He made it to two GS finals at age 39 only to be beaten
by a young Jimmy Connors. Then of course there was Laver who relied on
his serve and volley more and more as age slowed his step.
