I believe it. Davydenko is perhaps the 2nd best mover in the game and he's using Agassi's tactics of stationing on the baseline and taking the ball on the rise.
I remember Agassi causing huge problems to Fed in their RR match in Houston.
Fed's playing 1-2 steps behind and losing a bit of time there, but this is where his comfort zone is.
