Dana's comments about the KO on the upcoming TUF being the worst he's seen on TUF and maybe in MMA had me wondering what were some of the nastiest KO's in either. Aside from somebody running full speed into a knee or something I just can't picture a KO being that bad that's it worse than some of the KO's we've seen.
Some of the worst that come to mind on TUF
James Vick knee on Cruickshank
Riddle KO'ing that bearded jits guy to get into the house
Matt Brown head kick on that chew stealin Jeremy kid.
Some of the worst that come to mind in the UFC
