i think iron mikes the only possible winner if hes fit. When lewis fought Rahman, all his weaknesses were exposed. Tyson would blow holes in them. Tysons definitely too quick for Lewis.
yeah..lewis could win by a boring decision because hes slow and careful, but tysons also quicker and he may not let it be a boring fight. When lewis lost to rahman, he might have underprepared, but he still looked uncomfortable with rahmans punches. Id bet on tysonby knockout.
