Oh, I didn't know that, thanks. That is kind of discouraging, I didn't notice that during the fight (well, that's why I like to read the comments here - I wasn't on the forum that night). I thought GSP had too much integrity to try and get an unfair advantage that way.
Kinda changes things...
(Don't get me wrong, I'm a fan of BJ Penn too. Which is why his letter to the NSAC surprised me.)
