Another thing I like about St Pierre - is he ever NOT at a UFC show (barring the free Spike shows)? He truly wants to represent and be an ambassador for the sport and the UFC as much as possible. A guy like him could write his own ticket, but you can tell that he loves everything about being a UFC champion and a MMA fighter in general.
GSP says he wants to be known as the greatest pound for pound mixed martial artist of all time. To achieve his dream, he needs to move up to 185 and fight for Silva's title.
