To add to this, it is wise to remember that the peak of Tyson did not last long, so even if he is considered to be one of the best heavyweight boxers which ever lived, he was only able to maintain that level for a few years, unlike with what we saw with fighters like George Foreman, which is the oldest person to win the heavyweight championship of the world, so if Foreman had staged a comeback when he was Tyson's age, I would be more willing to believe he had what was necessary to fight professionally and get some wins.
He had plenty of fights back then looking at his record -

However, I think the main reason he has fewer fights compared to someone like Foreman is because he spent almost three years in jail. That time away from the sport was a major setback. Even though he fought more after his release, his momentum and career trajectory were undeniably affected.
Before going to jail, his record was nearly flawless with only one loss, which says a lot about how dominant he was. Being jailed wasn’t just a pause, it was the turning point of his career, and it’s hard not to wonder what could have been if those years hadn’t been taken away.
