Anyone who thinks Lewis was in his prime, physically or mentally, for that fight against Vitali needs their head checking.
Even so, look what an out of shape and un-focussed Lewis did to Vitali's eye. A focussed and in shape Lewis would have beaten the brakes off of Vitali.
Vitali wasn't a big name then too compared to now so I don't think Lewis had that fire in him. Once he had Tyson's name on his resume that was it for him.
