Rematch will give Machida an advantage for sure.

Shogun will need a better game plan to beat Machida, He has the skills but counter kicking is not going to do it, I think Shogun is afraid of the transition to the ground because he doesn't want Machida on top of him. If Shogun had a chance to do some BJJ and tire Machida maybe he could attack with some Muay Thai instead of defending and counter punching.
