with kalib,
Its one thing to backup for strategy, its another to run around the whole fight. I give him all the respect for going into the fight, but I honestly I would have rather had my hand broken or been knocked out. Its permentantly out in the world for the rest of your life.. you look like the biggest punk b---h.
Fighting on your back is a bread and butter tactic from "GJJ" and BJJ. Its doesn't take a rocket scientist to figure out its a hard position and its not the "best". That being said I would hope a person of Serra's skill level could have pulled something off better than that. I don't know the level of his injury... so maybe that played a big part in the fight. Half guard and full guard are not that bad of a position even in MMA. Granted GSP is a monster, so is Serra. Serra is no chump and he isn't fighting GSP out of pure luck.
