Okay, Novak Djokovic enters 2013 as the guy to beat.
He's the clear favorite for the AO, and time will tell if he is the one for RG, let's see how Rafa's playing and Federer is always a big question mark.
His 2012 WTF was pretty damn amazing, I think the result in the final could have been different, I think the match was decided in some particular points, but still, the guy was a deserved champion and here it is, as a solid world number one.
He has a tough year ahead, he defends a lot, and his 2 competitors defend in some particular times (Federer defends little points in the final part of the tour, and Murray defends nothing in the clay season and IW).
We don't know what's gonna happen with Nadal, but we know that after Wimb he doesn't defend a single point, so the big question here is "How many points will Rafa get in the first part of the year?" After that, we'd know if he's a contender or not.
Back to Nole. He can EASILY have a 2-slams year, it depends on the other players.
Why I say this? Because Nole has proved the world he can play in a solid level during a whole year, and that's something the other guys should accept.
Considering peak Nole is at 100%, we know Nole won't play below 70% in any match, so, if you are Federer-Murray-Nadal-Whoeverthefuckyouare, you need to play better than "70% Nole", and that's not pretty easy.
I think he'd take the title in Australia, Indian Wells, Miami, MonteCarlo and Rome. I'm pretty confident of Nole taking those.
That's almost unbelievable, 4M1000 and a slam before RG... Then, who knows?
I think he'd be the favorite for RG but I don't see him winning it yet... I even see Federer/Ferrer beating him there.
Wimbledon isn't the best surface for Djokovic, Federer/Murray can take him out with no big problems. I don't see him a the big contender in grass (still, we don't know).
The USO-Series are a 30-30-30% chances for the actual top 3. (except, probably Cincy where Federer has a 50% of the title in the bag before playing).
If the season goes as I think so, I think Nole will be too tired for that part of the year, so he won't repeat his 2011-super season.
I think he won't take big titles during the 2nd half, maybe Montreal, or Shanghai.
I see him finishing the year as world number one again, yes.
