The notion that older Heavyweights couldn't beat Heavyweight's the size of today
You always hear how Joe Louis wouldn't be able to beat an average Heavyweight today because of the size difference. But.....Joe beat Primo Carnera, who was like 6'5'' and 255-260 lbs in size. And let's not act like he was any less skilled than the majority of the heavyweights today (excluding Wlad and Vitali themselves of course).
But basically....given Joe beat a BIG HEAVYWEIGHT like Carnera in his day, do you think he'd be able to beat these big heavyweights today???
