Worst stamina

[Master]

Bruno had stamina issues and the top fighters knew they just had to take him to the later rounds.

The old Tyson after jail had stamina issues, he was finished after round 5 against Holyfield.

Tyson in general had stamina issues he only KO'd 6 guys after round 5 for his entire career and only ONCE did he stop someone past the 7th round. His record of fights that went longer than 5 rounds was 11 (6 KO's)-4 and for a guy sporting such an impressive record 50 (44 KO's)-6-0 that seems to show that if you could last with Tyson then you had a far better chance of beating him because he would tire out

Tyson started off fast and put a lot of pressure/energy early but he did know how to pace himself. Against Tucker he was fine after 12 rounds.

Tucker had a broken hand

Tucker used it a lot for a broken hand. Tyson also was not tired after Bonecrusher or Ribalta .

After jail he was muscle bound and was a shell of the fighter he was pre prison.
