BY all accounts Choynski was a murderous hitter but Marciano was a beast ... Rocky could be tagged and possibly dropped early as he was not a fast starter and was hittable but I can't imagine a scenario where Rocky dos not wear him out and ultimately stop him ..
I was always intrigued by Joe Choynski and I heard he was a powerful puncher and could KO anyone who he hit squarely. I think the issue here would be how well Joe could take Rocky's savage assault, it could end quick like Matthews or it could go a bit long like the Moore, Cockel beating but I think the quicker exit for Joe may be the way to bet, however I am sure Joe gets KO'd
With no real footage of Choynski, one has to judge by the record, and Marciano's is a mile better, and he also has a big size advantage. Joe's shaky chin is no recommendation against a puncher like Marciano.
