You cannot compare number of rounds to number of rounds, the variables are completely different in an MMA fight than in a boxing fight.
Most boxing matches are boring as shit because all you do is punch and clinch for an entire 12 rounds ( snoozefest ) while you are more inclined for an actual finish in an MMA 'bout because the fight can end in literally hundreds of ways.
Can you honestly tell me if you were to pick between boxing and MMA, you'd pick MMA because it's less tougher? I would probably do boxing because all I wouldn't have to worry about all this shit above.
If you were competing in MMA and someone knocked you down, they would get on you like a pirahna whereas you get a count in boxing. How is MMA not more challenging and tougher than boxing?
MMA fighters are inclined to finish? that's nonsense, how many fights at UFC 114 didn't go to a decision? 7 of the fights went to decision, and one of the KO's was the most ass lucky thing ever. No way in hell that should have happened. MMA has just as many boring fights as boxing. Very few MMA fighters go into a fight to end it, they go in to get a win.
Boxing is tougher because the fighters get a chance to semi recover, think about it, in MMA a dude gets smashed with an overhand right, falls down and his opponent is on top of him and the fight's stopped after a few light blows. A boxer smashes another with an overhand right, his opponent gets 10 seconds to get to their feet. Boxers take far more punishment, because a fighter might semi recover 6 times in a fight and get smashed far more than an MMA dude who gets smashed once and gets 2 hammer fists and it's stopped. Look at what happened to Ali getting punched in the head so many times. Doubtful any MMA fighters will ever end up punch drunk like that. Plus in boxing they punch 2 places only, the head or the body. Plenty of MMA matches end with no damage to either fighter due to one of them lay n praying their way to a win, or a lot of clinching against the cage. Boxers get punched in the face hundreds of times a fight, MMA fighters never that much. And as everyone knows boxers are far superior strikers, so getting punched 50 times in the head by Roy Jones >>>>> any MMA strikes. Boxing is far more technical because you can only win 1 way, you have to be a master at boxing to win. There are no take downs, no grappling, you can't win by laying on a dude for 3 rounds and if you clinch it's broken up in seconds. Many MMA fights are nothing but 15 minutes of clinching. Now I love MMA but boxing is on a whole other level. This is why world wide it's infinitely more popular than MMA.
