mmaswe82 answered it pretty well.
Mousasi kicked Mo's ass HARDCORE in that fight, Mo was battered and didn't land anything on Mousasi from standing or while on top or even any slams. Mo must have hated that fight so much, standing he was getting tooled and when he took Mousasi down he was getting beat up almost as bad.
But srsly if Mousasi read an MMA judging criteria book once he'd probably be the #1 LHW or close to it.
You must be kidding me. Mousasi and Mo showed just how far behind the UFC curve the SF LHW division is. There cardio was embarassing, not just Mo's but Mousasi's to. I remember watching thinking ha Mousasi is playing the Frank Shamrock/Tito Ortiz game and just letting Mo gas himself out and it was working. Then it became apparent that man Mousasi is just as gassed as Mo. That fight was abysmal and neither guy looked at all credible as a threat to the UFC LHW division.
