I honestly have no idea how that would turn out. I could see Moorer out-pointing the ponderous Giant, and, I could just as easily see Valuev turning out Moorer's lights.
Moorer. I thought holy beat valuev haye beat valuev. valuev seemed to do better against bigger slower guys than blown up smaller guys with fast hands. I don't think much of valuevs boxing skills either whereas moorer was an excellent boxer and fought southpaw. Moorer UD unless the fight is in russia lol
If it's on Russian soil - unanimous decision for Valuev. Anywhere else on the planet - Moorer by unanimous decision lol.
