Neither man had the power or punch output to stop the other. This one is bound to go the distance, unless of course a freak incident such as a clashing of heads leads to a stoppage, but its highly unlikely. Although these men were not exactly scientists, Chuvalo arguably had skills that were a tad more well rounded than the otherwise crude Tex Cobb. Of course its not impossible that Randall could win this fight too, considering that George lost to worse men, but I'd have to make Chuvalo the favorite by decision here.
