I think Shogun's fighting style is kind of tailor made for Machida. Highly agressive and very entertaining. The thing I kind of see a problem Shogun presenting to Machida is his ground game but, even then I think Machida's ground game is better. So as far as Shogun vs Macida goes I dont really care for it because I have a pretty good idea on how the fights going to play out.
Franklin vs Belfort is alot more interesting for me. On one hand I am big Franklin fan and I love that guy. On the other I want to see Belfort and have some matches against Wandy, Hendo, and Silva.
But, the most important match in my mind is Lesnar vs Carwin. This is the point where Lesnar is either going to show how truely limited his game is or is going to give us another era to the heavy weight division. Though I do think Carwin has a good chance from stopping Lesnar and bringing back a little more class from a champion. I mean honestly if Lesnar wins who is going to beat him. He has already fought two of the top ten guys in the HW division and beat them badly. Nog's style is going to get him knocked out. Sure his chin is durable as hell but, he stands straight up with not alot of head movement. Cain doesnt have the size. Kongo and Cro Cop dont have the takedown defense. Carwin is the best chance in the HW division and I hope he makes a shot heard around the world and takes out Lesnar.
