lol @ GSP leaving 170 to become the 155 champ. That is beyond retarded. I can see him fighting Benson at a catchweight if he beats grant and pettis though. I don't know if Benson would want to fight for the WW title at 170 because if he wins he has to stay there and the competition would be much harder for him without his weight advantage over a lot of his contenders at 155.
If you see Lethal Strike, don't tell him where I'm posting. I'm dodging him, I owe him V$50.
