Fighters that were shot in their 20s

[holmcall]

Actually, worse.

Mike Tyson was not shot in his 20´s. His last fight in his 20´s was the second Bruno fight. He was far from shot. He was shot in the Lewis fight and especially his last two fights. Shot means you can´t fight anymore.
At 29 he was on the slide, yes. Past his prime, yes. Not shot.
