You know Tyson probably did miss his calling as a MMA fighter....I personally have always felt the guy is vastly overrated as a boxer, but with an all around training in MMA he would have been a Fedor like fighter. That being said my issue with boxers, w/little to no MMA training, in an MMA fight is why would an all around fighter choose to "box" with him. Also I simply don't see boxing and mma striking as the same thing. I look at it like a baseball pitcher and a softball pitcher. Some end result and concept but with some fundemental differences. There are techniques taught in boxing that work b/c you don't have to worry about kicks, fighting from the clinch and takedowns. A prime Tyson had awesome handspeed and power so in any fight it would make him dangerous, but if I'm a MMA fighter or hell just plain old me the one thing I'm not going to do is attempt to "box" or trade punches with him. And if I'm a world class kickboxer like Mirko I'm going to use a variety of leg kicks and clinch fighting to slow down and frustrate mike then put him away with the most devastating strike in MMA....CroCop's left high kick. I don't give Mike anything more than a punchers chance against any top MMA HW
