Sherk doesn't get mentioned because you have to examine his UFC wins AT lightweight. They were Florian, Franca, Griffin and Dunham. The Franca fight had controversy with the failed test and all that drama and the Dunham fight many people had him losing that fight and didn't deserve the decision. Even if all 4 of those fights had been dominating wins by stoppage AND he hadn't gotten beaten so very badly by Penn he STILL wouldn't make my top 10 all time LWs. He just doesn't have enough top wins to qualify for me.
