Bubba Watson, 29

He's never had a lesson, and his swing thought can be boiled down to one word: kill. But the PGA Tour's leader in driving distance is no one-trick pony. He tied for fifth place at the 2007 U.S. Open at Oakmont, and he won $2.7 million in his first two years on Tour. He doesn't lack for confidence, either, despite going winless on the Nationwide circuit as well.
