Erik Paulson's a great submission specialist and comes from a great camp, but he isn't in any kind of shape to go the distance in a fight. At least, he wasn't at the HDNet fights in Dallas earlier this month. It didn't matter because he had Jeff Ford tapping early in the first round, but my point is that if you want fighting workouts you want to be prepared to go the distance (and Paulson didn't seem to be ready for that). If you're going to follow a pro fighter's training regiment I'd go with Randy Couture or Sean Sherk. Someone that has proven he can go the distance consistently.
Thanks to NikosCC for the sick sig!
