I've got to know, because knockdowns happen literally all the time in fights and the fight goes on. Here's the sequence in question: Yes, Overeem was wobbly getting up. Yes, his lip was badly damaged. Yes, Rosie would have probably finished the fight if he had followed up. But he didn't. I'm not in the "if he dies, he dies" camp by any stretch of the imagination, but plenty of fighters have been wobbled by a strike and then clinched or grappled or otherwise gave themselves time to recover. That's a part of fighting, and again, we see it all the time. We saw it on this very card in prior fights. So, let's put aside all the what-ifs and get down to the basics. Those of you who defend the stoppage, what do you consider a knockdown, and when should the fight be stopped or left to continue? EDIT: One more question to round things out. You often hear in commentary (especially Rogan's) about a fighter getting "rocked." But the fight goes on. So again, how is that different? For those saying a TKO is legitimate because a fighter is wobbly or not all there, should all fights be stopped as soon as someone is rocked? If not, where do you draw that line?
