I'd agree Norton would probably win, but he did struggle against oppenents who were stronger. Both have shaky chins and Frank had a lot of power.
Norton failed miserably against big punchers (Foreman, Shavers), but Bruno doesn't fit the bill. Ken would eventually stop Frank , after the 5th.
i think bruno would win this within 6 rounds....i know you cant compare bruno and foreman but kenny didnt like fighting big, strong, powerful guys and if anything, i think his chin is slightly better than nortons....
i see this one as being more competitive than most of the posts so far. norton was great and awkward but he was rarely a banger. bruno had GREAT physical power and though he wouldn't push norton around he would have the edge on the inside, at least in terms of clinches. i see bruno getting an early lead but by the 5th norton was start to figure him out and time the jab. with the great eddie futch in his corner, norton would start to wear and walk bruno down. by the 11th he is being ground down to powder and the referee steps in to stop it at 2:11. norton wins based on superior strategy, fantastic jab and the ability to counter-punch bruno
