By all accounts, Jonathan Little is one of the most successful live tournament players in the history of the game. He's got $6,388,782 in live tournament earnings, built largely before high roller events really skewed earnings numbers in poker, and two World Poker Tour titles that helped him earn WPT Season VI Player of the Year honors.
Of course, he still plays regularly in high stakes tournaments around the globe, but these days, a lot of his time is spent making an effort to grow the game and help those who want to get a whole lot better at it.
