If Conn could box those three contenders as he did against Louis he would have a great chance to win. Conn was a Master Boxer with some pop and if he didn't get caught late he might have stolen one from Louis. Conn was a fighting LtHvy since 1937, although light at the beginning was a solid LtHvy by the time the 1940s began! Louis was not in his normal top condition weighing 12 pounds or so over his best fighting weight at that time. Its not an excuse and Joe didn't use that way but its a fact!
I'm almost certain the contracts for Louis as the champ always had returns along with partial payments to Braddock from contractual obligations.
Conn would obviously have more clout today with that win but it wouldn't increase his skill level or overall talents so it shouldn't have anything to do with how he's judged. Ray.
