Well no offense to anyone becuase I do like boxing, but there just isn't even a comparison to be made. You could put the best boxer next to the best mixed martial artist in the octagon and chances are, the boxer is going to get demolished. Honestly WTF would Oscar De La Hoya or Hatton do if someone threw a Thai kick at their thigh? (besides fall down); and vice verca if you made a mixed martial artist play by boxing rules hed probably get messed up. And as far as straight ram muay/kickboxers go striking in MMA is just a different game. It's a lot easier to clinch with someone, throw head kicks etc etc, when you don't have to worry about being taken down and choked unconcious.
