Herring isnt a fighter thats easy to finish. In fact hes one of the hardest fighters to finish in the sport. So even if hes a mid level fighter, unless you have cro-cop's kick, and you land it to his liver, nogs jits(which 2/3 of the time wasnt enough)or the explosiveness of Fedor to cut and continually pound on the cut until it tears open; Youre not going to stop Herring short of an injury.
No one has.
