Tiger Woods: He looks great, he's hitting it a mile, and he has played well of late. But remember, he hasn't won a Masters since 2005, and it is possible for Tiger to play well and not win. Also, Woods is ranked 103 in the world. Since the world golf rankings were created, the lowest-ranked player to win here was 69th — Angel Cabrera in 2009.
Phil Mickelson: At 47, he can become the oldest Masters winner ever, he's playing well, and he could tie Tiger and Arnie for second all-time with four green jackets. Plus, he's Phil, so if he plays well he'll be good for four days of incredibly intense storytelling and scientific analysis of every one of his flop shots.
Rory McIlroy: For the fourth straight year, he will try to win the Masters to become the sixth player to win a career Grand Slam. And he's only 28.
Bubba Watson: Can he win a third Masters before he wins another major? Yes. Augusta National was made for him. He can miss with his driver and survive, he can punch out between trees, he can handle the slippery greens. It doesn't have to make sense for it to happen.
Jordan Spieth: He has already created a lifetime of stories here, narrowly missing a win in his first start, running away in his second and hitting two shots into the water on No. 12 on Sunday two years ago and still finishing second. If he putts well the next few days, he can win.
