Overrated - Conor... the guy is still listed on the P4P lists and showed that pound for pound he can't beat a top 5 guy one weight class up.
Underrated - Lawler... he is never mentioned in the top 2 or 3 P4P discussion and I think he has the best recent resume of anyone, he also has the longevity and I think if he wanted to he could go up and beat Rockhold tomorrow. I hope he gets the GSP fight and puts himself in the context of the legends by beating Georges (nothing against GSP just like Lawler).
