Prime for Prime fifteen rounds- Does Larry's mix of power output and aggression succeeded where the grace of Ali failed the first time? Personally I believe Joe breaks him down in a more brutal fashion then Ali and TKO's Larry by the twelfth.
Stone cold classic. I think prime Frazier might have had too much for Holmes and stylistically would have given him a lot of trouble. So, I pick Frazier by decision but in a very great fight.
Frazier by decision. I think he would score a knockdown, but Holmes would be right back up and at it. I actually think a (prime) Holmes puts a better fight than FOTC Ali.
FOTC Frazier by decision or late stoppage. It would be a GREAT fight with neither warrior giving an inch. Both would be well and truly beat up by the time the dust settled.
