I think Tyson in his prime was pure quality. He slipped with getting rid of Rooney and then the Douglas debacle. But he was still a monster prior to jail, being able to just 'nuke' it out with Ruddock rather than using the full range of skills he had previously.

The thing that ruined Tyson was 3 years plus behind bars. He wasn't quite the same and I don't think Holyfield (and definitely not Lewis) beat anything near a prime incarnation of Mike Tyson. Tyson stuck around as a carnival show attraction in his later years and the losses to Williams and McBride were were just end of the road blips. But for those few years, Tyson was everything you could want in a heavyweight fighter.

He's a fighter you can always go back to and watch again and again.
