Yeah, but boxing is a much older sport and has older organizations who all have had more supposed influence on judges because of deeper running ties. They also have more competition between orgs and cross org fights, so there is more incentive to rig the judges. Nationality seems to be a bigger aspect in boxing too, like Mexican fighters will probably get preferential treatment from Mexican judges. Though I'd say that Brazillian judges in MMA have been pretty partial in the past too, for instance. But that is separate from the org's involvement though, IMO.
But the main thing is just the seemingly genuine emotion with which Dana shows, and has a hard time to repress, his frustration.
