If you have been following mma, your first guess should be that the Wrestling guy will hold the Karate guy down and not let him get back up. But, and if you have been following, you will know that Lyoto is excellent at staying to his feet and if he does get taken down he can literally pop back up. That will mean that both fighters have to keep it standing which is the main strength of Lyoto Machida.
Now, the other major weapon that Randy has is pinning Lyoto up against the fence and he might do that a few times to Machida, but, I don't expect him to keep him there for long as Machida is an escape artist in the ring.
I predict that Machida will KO randy in the second round of the event.
But.... As Always...
Good luck to both of these Gentleman and
class acts!
