Oh yes the defense is entirely different in MMA. When boxers fight in MMA they usually lose when they fight guys that kick as they aren't used to blocking kicks, see Ray Mercer.

Sure there are boxers who have bad attitudes and tribal tatoos but boxing isn't marketed 100% to and for a specific type of person like MMA is. Just watch the commercials when The Ultimate Fighter is on.....don't blame me for calling the sport out on it, blame Dana White he's done it to the sport.
