Each fighter can only change so much in the time between fights, they won't completely change their style. And stylewise, Rua takes it because of the way his body is built, it gives him more power behind his kicks and Machida's leaning back will open him up to kicks every single fight. This time, I see Rua getting Machida's rhythm down even more and taking him out in the third or fourth round. Unless Machida starts to lean forward, he will get kicked in the legs and tko'd. Rua does not fear getting hit, he gets knocked out in training, Machida's counter punches are not feared by Rua.
