I think ppl generally overrate the size factor hereThe thing is between Spence and Crawford is size difference playing a major key. Errol is still looking up while Crawford just reached his comfortable weight. Spence at middleweight could be what Crawford is to welterweight now.
Horn obviously isn't as good as Spence but he is also a big welterweight and a physical one. Crawford didn't look noticeably smaller than him in the ring and he could bully him on the inside as well.
Spence might be even a little bigger than Horn and he might have more physical strength too (don't know for sure) but at least that tells me that he woN't be able just simply overpower Crawford based on sheer physicality.
Spence will be bigger and possibly stronger but I doN't think that the difference will be so big that it will decide about the matchup.
