Mike Tyson has singled out his 'smartest' opponent from a career that featured wins over Larry Holmes, Frank Bruno and Evander Holyfield. Iron Mike, who became the youngest heavyweight champion of the world in 1986 at the age of 20, will go down as one of the all-time greats.

Though Tyson fought at a far superior level than Paul has ever done, Davis argued that because of the creator-turned-boxer's 30-year age advantage, together with his physical assets over a near-60-year-old, it was always going to be a mismatch from the start — and a fight that should never have been made to begin with.
