Is Djokovic's forehand less Western than before?
Looking back at some old matches of Novak, and his forehand grip appeared to be much more Western back then. A couple good examples to watch on youtube: 2008 Miami vs. Nadal, 2005 Aussie vs. Safin, etc. Has there been a dramatic change to his grip... or a slight one? When did it happen and was it with the switch from Wilson to Head? Back in 2008 he was much more likely to hit loopier forehands, some of which landed very short in the court - these days his stroke looks different, and he is getting much more consistent depth.
