I give Moore a slight edge here, but it would be a tough close fight and Spinks could take the dec. Spinks would be as good a 175pounder as Archie ever beat and vice versa.
I find it interesting how many here are picking Spinks when Moore had so much more experience against top level opposition .. Spinks was taller by 3" but their reach was near identical, maybe a shade for Spinks .. no doubt Spinks was a great fighter but to be so favored over Moore , I'm not sold ..
