With a 13-0 start and two tournament titles to his name, Novak Djokovic is one of the most unstoppable forces in all of sports.
Djoker is playing tennis at a level that simply can't be touched by anyone right now. The question is, how long can he continue this dominance?
He's already claimed one Grand Slam tournament title. He breezed through the Australian Open field. Outside of a small hiccup against Stanislas Wawrinka, he had no issues claiming his first Grand Slam title of the year.
Winning all four Slams in the same year has been just about impossible. Only Rod Laver has done it in the common era, when he swept all four tournaments in 1969. Roger Federer has come close multiple times, only to be thwarted by Rafael Nadal's brilliance on the clay of Roland Garros.
So, what's the likelihood that Djokovic can pull off the feat? Let's examine.
He already has step one out of the way. He opened up the season with a win at the Australian Open.
Next up is the French Open. This will be the most difficult step for him if he wants to complete the true Grand Slam.
In 2011, Djokovic was just about as dominant as he's been in early 2013. He breezed through the Australian Open and was the No. 1 player in the world. Unfortunately, the clay proved to be his undoing as he lost in the semifinals at Roland Garros.
He went on to finish out the season with wins at Wimbledon and the U.S. Open. Three out of four Grand Slams in a season—close, but not quite.
This year, his chances at the French Open are much better. Defending champion Rafael Nadal will be back to defend his title, but he was forced to miss the Australian Open due to injury.
Nadal has since earned two appearances in finals, winning one of them, but it's unclear how he will fare against elite competition. If Djokovic is ever going to win the French Open, this is the year for him to do it.
Should he win the French, his chances of earning the Grand Slam will shoot way up.
He's playing at an extremely high level right now and has proven he can win both Wimbledon and the U.S. Open when he's on top of his game.
He holds a combined record of 71-14 in both of tournaments and won both tournaments in 2011. Andy Murray and Roger Federer will certainly be there to challenge them, but he's already proven he can beat Murray on the big stage and went 3-2 against Federer in 2012.
The French Open definitely looms large as his biggest obstacle, but a win there would set up Djokovic for a legendary 2013.
