People in mma won't go to boxing because it's harder. No disrespect to MMA im just saying its a way more difficult because your only options are your hands. In MMA there are way more options to master and ofcourse you can't master them all. For example if your going to fight a guy that's a great kick boxer you take him to the ground. If he's a great wrestler you stay away and keep the fight on your feet and if your even you fight to see who's better. But in boxing if the opponent is a better boxer there is no way of beating him. That is why it's more difficult. So boxers could go to a cage and still win aslong as they're not taken down. But if an MMA fighter goes in a ring, his hands are his only options and obviously you'll never beat a guy that's been perfecting one thing while you TRY to perfect many things.
