Fighting Vidios on the Streets?

I love to watcha fighting vidios because there's so much to analyze. I don't see actually, a lot of in to the ground, unless the guy gets punched and then he falls to the ground. Almost every fight that i've ever been volved in or witnessed did involve some type of a clinch at some point or another. And therefore, you know, i try to build that into my training,. So we do spend a lot of time working on vertical grappling.
