Nah, HW would be bad for him IMO though he could beat some top 25 guys. Unless he can't get any decent paying CW fights, he should stay there and try to finish his career strong there
He can rule cruiser, it seems perfect for his body size. He already decimated Huck. He is a very good fighter. Just not big enough.:good
I agree with those who say he should stay at cruiser. He lacks punching power to be a smallish heavweight, unlike David Haye. I remember in his fight with Adamek he threw a perfect right at Adamek, straight from the shoulder, fully extended his right arm, landed sqaure on Adameks' jaw, Adameks' head span round but other than that he kept on coming. Adamek's tough but he's hurtable, and if you can't even wobble a guy like that with your best shot you ain't got one punch power. Cunningham does have skills but I doubt that'd be enough to carry him against bigger guys who can hurt him.
