Talking about the best (if there is such a thing as the best) all around fighter doesn't necessarily mean who's on top of a weight class at the moment. When I think of good all around fighters, clearly gsp comes to mind, so does carlos newton, bj penn, caro uno, genky sudo (no flaming my spelling). Were talking well rounded as in skills in many disiplines not a wrestler with a good punch. Or a puncher with good takedown defense. Saying Randy Couture is a well rounded fighter is absurd. Randy will always be Capt. America to me, but his skills are limited. He's very good at what he does, but hes not will rounded. That goes for matt hughes and a lot of other names I saw thrown out there.
