In the 3rd round... the ref motions for them to continue. Red(person with red headgear and gloves) seems to tell his corner he doesn't want to fight anymore. You can see his corner throw the towel in the ring, ending it?
Lack of cardio? Excruciating pain / injury? Accidental headbutt?
Anyways... Red seemed to drop his hands a lot, but somewhat made up for it with his level changes and connecting from the outside. He threw punches from angles where blue couldn't see them coming, sort of like how Hardy didn't really see that punch from Condit coming.
Blue may have had better technique, but was too complacent. He didn't give angles, move his head or bother to counter sort of like BJ not bothering to throw back against Frankie Edgar. He pretty much plodded forwards predictably, Gabriel Gonzaga style, and was out-gunned, out-maneuvered and out-boxed, at least in round 1. Too much respect from blue in the beginning. He turned it up in rd 2 and towards the end, though.
Honestly, you should probably talk to a professional, though.
