Pre Prison Tyson was still a force, a diminishing fighter, but still dangerous even after losing to Buster, poor trainers, King taking over and failing marriage.

Post Prison Tyson was a shell with no real substance. He was muscle bound to hide his lack of boxing skills, carefully maneouvered to the title by King/corrupt WBC and surrounded by ass kissers. This Tyson was exposed by the first real fighter he faced which should have been Lennox.
