With each in their hayday, I would say Will. I have watched this show since the beginning (2000) and Will has always been the ultimate player to me. Will just had a good poker face and really had nothing to lose (he was a doctor for goodness sake). He just wasn't desperate and never begged. I never understood all the Dan love. Can't remember much about his second time, but first time he was just surrounded by fools, who didn't really understand the game. Will came into All Stars, with some die hard players and still went far!!
