Lewis and Holyfield were both late bloomers. Nowhere around when Tyson unified the Heavyweight title. Neither of them spent 3 plus years in prison away from boxing either.
Lewis definitely was a late bloomer.
Tyson's peaked in the mid to late 80's, Holyfield in the early to mid 90's and Lewis in the late 90's.
This is why I don't understand when some morons bring up the similar ages of Lewis and Tyson when they fought. Their ages are irrelevant.
Lewis was in and around his boxing prime at the time of the fight while Tyson was well over a decade past his.
