Yeah but this is also a ****er that stated in an interview after winning a fight that he had a broken back in training camp, so i wouldnt trust his self diagnosis.
i am amazed tyson had breathing problems. because his boxing style expended more energy than any other style and when he was with rooney the only time i saw him even breathing heavy was in the last round against tucker . tyson had as good as stamina as any heavyweight in his prime .
Tyson never had good stamina, he was hell in the first 2 or 3 rounds, after that he just fought with a lot less intensity..
