Douglas would be a huge problem for Frazier due his huge reach, weight, height, advantages. And Douglas when he's on song knows how to fight like a big man aswell and use his excellent jab. The issue is Douglas wasn't really tested by Tokyo version of Tyson and I think Frazier would ask Douglas alot more questions with his relentless attack. I've always doubted Douglas could win a battle of attrition which is why I'd be hesitant to pick him over a peak Frazier despite his physical advantages.
Buster looks like a million bucks and is ahead... until Frazier starts smokin'. I don't think even Tokyo Buster had the conditioning to ward off FOTC Frazier. I think this would be on of those cases where one mans peak performance, brilliant as it was, still falls short of anothers peak, in Frazier's performance against Ali.
FOTC Frazier's too tough and too well-conditioned even for the Tokyo version of Buster--KO or stoppage by Joe 8-10 rounds max.
