Tyson got a well-deserved time-out from boxing after his incident with Holyfield. Still, history has proved that, if a man wants to fight, he's going to fight. Don't confuse the capacity for rebirth with reinvention, though. When Tyson scored a match with Francois Botha in 2009, he was the same old Mike.
The good: he showed flashes of his old dominance, with a massive knockout punch to claim the victory. The bad: saying he expected Botha to "die" before the fight and allegedly trying to break the South African's arms during the match. His victory put the boxing world on notice: Tyson was back. And he was still troubled.
