That is a great question, as Marciano's latest biographer (Redemption: The Life & Death of Rocky Marciano - due to be released soon initially as an ebook) I can tie these two together to an event that almost happened, after Louis' defeat at the hands of Marciano Robinson planned his revenge, first he was to fight Maxim for the light-heavy crown then he would move up to heavy and fight the rising contender Marciano before having a crack at that title too. As we all know now he lost the title challenge to Maxim, more through the heat than the superiority of his opponent yet still he hankered after facing Marciano in order to avenge his friend, that is until Louis himself advised him against it...It is a shame that the fight never happened because it would have answered many questions regarding these two legends...
