re: UFC 156 - Frankie Edgar vs. Jose Aldo for the FW Belt --------------- (2/2/13)

Knockouts and submissions are very different.

Knockouts can come from nowhere if you just happen to land a very clean punch. There are a ton of punches and kicks thrown in a fight, so the longer you are trading punches, the more likely you are to get knocked out.

So it's always risky to stand and trade, even if Rampage isn't that good anymore.

But with submissions, it is all skill. You don't just luck into submitting somebody. So if you haven't had a submission win in years, it isn't like knocking somebody out where you just didn't land a perfect punch, it means the other fighter can defend against your submission attempts.
