Yeah i agree he would have trouble in LW against fighters like Pettis, BJ, perhaps Frankie and Gray. But Jose belongs at FW, I think he is faster then all 4 and has better striking then them too.
I see him losing handily to Gray, Edgar, Penn (if he moved back down), Florian (this fight might actually take place), Melendez, Alvarez, Jim Miller, and others.
I don't see him beating any top 5 and I see him struggling against any top 10.
Keep in mind, I'm not saying he's a crap fighter, and I do have respect for him and I'm a fan of his, I love his fights, he's exciting as hell to watch.
However, I don't get carried away about his status because I'm a fan. He's in a very, very weak division where bottom of the heap LW's can become #1 contenders.
