Rocky Machiano vs Jim Jeffries

I know they fought in completely different eras but they had a lot of similarities. Both were strong ,crude, powerful brawlers who retired undefeated. (Jeffries would be lured out of retirement 5 years later to be cannon fodder for the great Jack Johnson) Both were always in tremendous shape and had incredible heart and durability. My prediction: This fight turns into a bloody brawl with a lot of holding and hitting and a few knock downs. In the end Rocky wins by attrition with a ko or tko in round 14. What do you all think?
