The top tennis stars face significant obstacles at the 2014 Australian Open. The strange thing is, none of them are looking at the same challenges.
Roger Federer is being betrayed by a limb that he just can't seem to get under control. Juan Martin del Potro can control himself, but what about the rising temperatures in Melbourne? Finally, Andy Murray is back, but did he bring his back with him?
Speaking of backs, will David Ferrer hold himself back once more?
The top two players in the world, Novak Djokovic and Rafael Nadal would seem to be their own special nemeses as the Grand Slam season opens.
But that's not true, either.
Djokovic, despite being ranked No. 2, feels like No. 1 in Australia. If he finds the same magic with his new coaching arrangement, he won't have any obstacles confronting him. He'll be free to become the one problem Nadal must do away with if he wants Australian hardware.
Time will tell which hills are simply too high to climb.
