I see the Heavyweight division with regards to the title playing out similarly too the Light Heavyweight division. I cant see one guy dominating for an extended period, rather i believe that the title will switch hands on a relatively regular basis.
I think you have a pretty clear top 4 in the UFC HW division - Cain, Brock, JDS and Carwin. Cain has beaten Brock and Brock has beaten Carwin. The ironic thing is that i have Brock beating everyone except Cain, but i think Cain would loose to Carwin. I think JDS would beat Carwin, but loose to Cain. Hence the division is probably going to go around in circles for a while, with Mir hovering on the outskirts, until some new blood is signed up to give the division a boost.
Not that it desperately needs it, its the best it has ever been. But it can always get better.
I would like to see Overreem signed up quickly as possible. I would also be interested to see Werdum make a return, and in a little while, Cole Konrad. He is showing some good promise over in Bellator.
Within the UFC there isnt a whole lot of young blood that is setting the world on fire. Although i will be keeping my eye on Morecraft.
