He would be among the top 3 or 4 best in the world. He'd KO Jimmy Ellis, Jerry Quarry(well TKO him anyway), Earnie Shavers(that'd be an interesting one), and Kenny Norton. Him and Fraizer would be real close, I'd give the edge to Joe though. But b4 he even got to Ali here is where is down fall would be...George Foreman. He'd be knocked silly. He'd also probably get a good ass whippin from Ron Lyle as well.
