Since Djoko's pre-Australian Open title defence hick-ups, he has been remarkably solid. It's funny, as 3 and 4 are always on opposite sides of the draw in big events, he's only played Murray once the whole year (l. final of Miami). He went 3-2 vs. Federer but lost the two that really mattered (US Open semi + Cincy final). Djokovic is a very deserving world number three who just needs to break his Slam final/ Masters Series win draught.
Yep he's got to beat a big dog at a slam, got to win a semi or he's a wasted talent. Although talent is mental as well as physical, so maybe he isn't that talented?
