It affected him but it’s way over exaggerated. He was still in his prime when he got out. ****, Lennox was a year older than Mike.
Tyson literally never beat a really good or great boxer. They lined up tomato cans sometimes two in a month to pile up victories. It was a very watered down division. He fought Mostly mediocre boxers that were already defeated before the bell rang. They also picked his opponents well, finding mostly journeymen or washed up guys like Holmes.
His out of ring issues and other issues were always there , it just wasn’t an issue until he started getting knocked out. Then it’s the excuse why he wasn’t Ali lol. It wasn’t prison , or the other issues that exposed him, it was when guys were like “ he’s not unbeatable “ and they saw him get his lights turned out. That’s when his career ended.
And I was a huge Tyson fan growing up and saw all his fights. I just know it was a mirage.
