Shown he has more power against who?? The 155 little guys he beat up on, again not impressed. He was getting outstuck by Hughes in RD 3 before he got taken down and finished at 170. the same Hughes GSP KTFO.
Gomi is a little 155 guy. He beat down a 185 Renzo and Penn had already killed Hughes before and was winning until he gassed in the 3rd. Again unless he gasses again, BJ wins. And i personally don't see that happening. He is a different fighter and wants to win this very badly.
Penn has shown he can gas at 170, especially when the pace is pushed on him. And GSP had a bad first RD against Penn and came back to fight 2 good rds on him. He has 2 losses, on his record both avenged. Saying he is not tough in a bad spot is not fair. Especially when Penn has shown far more weakness.
I said Penn needs to improve that and that is what will beat him.
Whatever his cardio is, it won't be where GSP's is, you can take that to the bank. He is fighting a guy with a ton of physical tools on him and is a natural 170 pder. I predict a long night for Penn, or maybe a short one
You are really underestimating BJ.
