I think anyone that fights at heavyweight and actually TRAINS these days has a good shot, but from what I have seen of him here are the pros and cons.

PROS:
Good size
Nice Handspeed
Atheletic and has good coordination for his size.

CONS:
Hasn't had his chin truly tested yet and as always that's not a great thing
His defense is lackluster against guys he outclasses
Stamina is ALWAYS a question with heavyweights him included.

He could be pretty good or he could be Audley Harrison, I think it's going to be somewhere inbetween.
