a great boxing match can be a thing of beauty, but for the most part, boxing lacks flow. a boxing ref is constantly breaking up clinches, making for a staccato spectator experience. MMA fighters are allowed to do their thing with minimal interference from the ref, as long as they're not pulling off disallowed moves, so they have enough space and time to find their combat groove.
what i also like about MMA vs. boxing: in MMA, if the headliners suck, there's a good chance that at least a few of the other 6 to 9 fights are going to rock on any given night.
agree, adabisi—a rousey-holm rematch is going to be interesting on many levels, particularly since holm was the only fighter to have given rousey serious competition.
