was before Ali beat him twice. Ali was never knocked out until he was a shot fighter close to 40 years old. Watch him in black and white vs Zora Folley, before Ali had to retire in his prime for 3 years due to his legal draft issues. Tyson would have been frustrated. Ali would not have been intimidated in the least by the Tyson hype and Ali could take a punch like few others. His speed was unmatched. Tyson would have gotten frustrated and tired out as he did vs Douglas and Holyfield.
