I was in the Sharpstown area (not a nice hangout place). When two guys squared off. One was a lanky guy ~ 6'3" maybe 190 and the other was stocky ~ 5'10" 210.
They exchanged body language that I could tell was leading to a fight, so I watched from a safe distance. The stocky guy shoved the taller one and the taller one started to punch, but it was a punch like he was playing a drum, kind of like a downward hammer fist (for you karate guys) but kind of like an overhand with very little body mechanics.
Anyway the punch landed on the stocky guys collarbone and he brushed it off. The stocky guy tried to tackle, but was trying to use his upper body too much (like he's trying to bench press) so the tall guy clinched and the tackle attempt didn't do anything except waste energy. They cirlced around each other while in a clinch while throwing rabbit punches at each others head and shoulders. Finally the stocky guy pushes the taller one and the tall guy trips, but gets back up where they continue to talk trash while the tall guy throws more downward drum overhands and the stocky guy throws haymakers. The punches make the expected smack noises but since they're using all arm, its only causing little welts and the punches aren't rocking any of them.
Don't get me wrong, these guys looked ferocious but they weren't hitting each other with much power, had very crude grappling skills, did not kick to the legs, did not knee, did not elbow/headbutt or dominate in the clinch.
Fights like this one and other ones I've seen reinforce my belief that stand up skills are crucial in a physical confrontation, whether its judo or kyokushin karate. I thought about the fight afterwards...how a judoka would have used the clinch for ippon
seo nage or ogoshi(?) even a leg reap since the guys were allmost upright. The boxer would have closed the distance fast and thrown short rights and hooks, maybe work for an uppercut/hook combo on the seperation. The thaiboxer would have taken out the legs ASAP with low kicks, control the clinch and fire knees/elbow at will from the clinch. The karateka might have fired kick combos to soften the guy up and attempt a series of palm heel strikes, knife hands or spear hands.
