Why would you pick an MMA fighter? Especially if they need to follow the rules.
I'll restate the point that I was trying to make with this: that street fights can be, and often times are, won by using only techniques that are allowed in MMA promotions.
This time around, I'll even cite an example: Kimbo Slice's backyard fight videos. We don't even have to do MMA, we can just do boxing, which is even more restrictive: in the majority of his videos, everything Kimbo Slice did is permissible in boxing. He fought strictly using his fist only, while most of his opponents used all eight striking points and grappled.
That being said, if it's possible to win real fights using only techniques that are allowable in combat sports; then that makes combat sports real fights.
