Vitali is a worst match up for Tyson then Lewis is because at least with Lewis he can be chinned. Vitali was never even knocked to the ground in his boxing career his only loses were with a dislocated shoulder and a cut stopped fight he was winning before hand. Tyson great but he was king of beating the bums in his time as well his best win is a 38 year Holmes which is a good win but common on now. Vitali is not his brother he is even more awkward, has far more killer instinct and has most likely the best chin in hw history i say that because what champ has never been floored as a hw. Tyson has a lot of match ups he can win with atgs in prime but Vitali is just plain bad for him.
