If you go with what's 'on paper' --their records-- it would seem logical to pick Rocky. If you're going with instinct, intuition, or a gut feeling about who was likely to get to the other's chin faster, then you pick Dempsey. It's logic versus instinct, and one never knows who wins this battle.
No inside game, can't take a punch so not durable, knows he can't take it so is extremely cautious so he grabs and hold each and every time at close quarters, straight up stiff Eropean Olympic style. No trainer or writer who saw them both picked Rocky to win.
Of course they didn't! Dempsey's and Rocky's primes were approx. 30 years apart... so these trainers and writers must have been young men when they saw Dempsey, and seasoned veterans when they watched Marciano. So isn't it more or less a given, that they would have been more impressed by Jack? IMO, these polls from the 50's - naming Dempsey the greatest heavyweight ever or picking him to defeat Marciano - don't mean a thing, and can't be taken as proof of anything!
It means that those who had the great privilege of seeing both of them had a unique opportunity for first hand comparison ,and they all picked DEMPSEY! What import you give that is up to you.
Silly. Ray Arcel Boxings greatest trainer chose Dempsey, Louis and Ali as his top three. Dempsey no 1. If you know boxing and just watch both men fight Dempsey was by far and away the greater fighter. Different leagues of talent separate the two. You cannot compare Marciano to Dempsey except as a puncher. Dempsey was the much higher skilled hwt.
It shows you the sorry state of hwt boxing today that a fighter such as Wlad stays at the top so long. He was embarrassingly koed three times by nobodies. Ross Purity was the king of bums and he knocked Wlad out.
The fact that his next opponent is rated no 3 and has not beaten a top ten heavyweight is also rather telling.
To say that plain "nostalgia" was the reason why virtually a vast majority in the time of Marciano's title reign, of veteran boxing people chose Dempsey to beat Marciano both in their primes is WRONG..These same NOSTALGIC boxing scribes CHOSE Ray Robinson and Willie Pep as the greatest Welterweight and featherweights they had seen also...Ezzard Charles was so highly placed as an alltime lightheavyweight by these same people...WHY, why, why is it always Dempsey who is always the man with the bullseye target on his back ?" If something is good for the goose, it's good for the gander", I should think...You don't like Dempsey ?. FINE, but millions of others who saw him, read about him , and found him great at his prime differ with you, and that resonates with me...
