There are not many boxers who would be successful in MMA. The ones who could pull off victories would be guys with super fast hands and loads of power.

I think a prime Tyson or Jones Jr. could have been successful, simply because they could potentially end a fight quickly before the fight ever got to the ground.

On the flip side of the coin, not to many MMA fighters would be successful at boxing either, they would get their asses handed to them.
