couple things
A) that was no street fight
B) who was the mma fighter and who was the streetfighter? I currently have no sound on my computer.....so the answer was probably there, but I couldn't hear it. The guy that won I'm "assuming" had the MMA training......he punched alot better, but his groundwork was WAY better. He passed guard was too easily.
but in all honesty.....in a streetfight if you take a guy down you're likely to get your eyes raked out or your throat hit before you even finish the move. And in streetfights it's almost never one on one anyway......so ground and pound is a no no.....unless you "like" getting kicked in the mouth.
