Id bracket mine:
I want to see Carwin fight a striker, i think he'll get knocked out. Mir will kickbox with Junior foolishly. Lesnar will have a very tough fight against Nelson. And Gonzaga fights like Cain on the feet.
Schaub / Carwin v. Junior Dos Santos
Roy Nelson v. Cain Velasquez
Because - Carwin v. Junior is the battle of the two hardest hitting guys in the UFC, and Nelson v. Velasquez is a fun fight. Someone's gotta fight him after he upset's Lesnar
Then you get Cain v. Junior in the finals.
I personally think Strikeforce has a better HW division right now.
