Frazier was not susceptible to being overwhelmed, but Foreman is simply a bad style matchup. There wasn’t much he could do because his weaknesses played right into Foreman’s strengths.
The fact that Ali was not able to dispatch Frazier in the same fashion doesn’t make him the lesser fighter, despite your flair for the dramatic.
Basing your argument on Ali and Foreman’s performance against a similar opponent, is like comparing their performances to Jimmy Young.
Not really. Frazier didn't belong in the ring with Foreman. Just that simple. It was like a champion beating a journey man. It was that much of a difference.
