I agree with the point that by the time Tyson ever went down, he was exhausted and had accumulated a significant amount of punishment. Mike definitely had a solid chin, as evidenced by some of the bombs he took from Ruddock, Lewis...etc. I consider Evander the greater fighter (both p4p and at heavyweight), but Mike was more consistent prior to the Douglas fight in my opinion. I place his being the youngest to win the title and clean out the division as equal to rising from a knockdown to win.
