Yes, he's one of the last HWs that needs to be signed back into the UFC.
For him it's 90% mental. If he's mentally prepared then he'll be legit top 10. He's got the best combos at HW.
A rematch against BF is due.
I'd like to see him fight Roy Nelson again. I think he matchups up favorably vs Werdum still as well. Good enough to stay off the ground and Werdum doesn't have to power to hurt AA.
