I'll tell you this if I'm the trainer for Fedor or Mirko against 88 tyson with no cross training I'd work MT leg kicks and mix in an occasional high kick to keep him honest...During training I'd put a premium on cardio and movement. I'd make mike chase us across that ring and everytime he set it would feel like a baseball bat on his knee. I'd want to pound that lead leg to point it slowed his movement and sapped the power on his punches...Then I'd put him on his back GNP or sub him...Obviously boxers throw punches with better technique for the most part, but with out good cross training all they can hope for is essentially a punchers chance.
