If Horn beats Crawford we’ve all been swindled into believing Crawford is 1 or 2 in the p4p ratings. It would be a colossal upset when Horn barely eked out a questionable decision against a shop worn Pac. But everything is possible.
In regards to Horn vs Spence, I don’t think the result would change. Crawford fights well on the back foot, only way he’d lose to Horn is by not handling his aggressive physicality and conceding his space. I think Spence is just as big and strong as Horn and won’t be bullied around the ring.
Styles make fights do there is no guarantee of anything. The only way Horn can beat Crawford is to impose his size and rough him up and wear him down. He can't do that against Spence. He has zero chance against Spence if by some miracle he gets by Crawford.
If he beats Crawford his odds of beating Spence would increase a lot. Right now I give him almost no chance to beat Crawford and no chance at all to beat Spence who I consider better than Crawford at welterweight. I don't think Horn is a good fighter or a worthy champion. I thought a sub par Pacquiao clearly beat Horn and was home country robbed. Horn was allowed to fight an incredibly dirty fight without even a warning for his many fouls.I think once Crawford KOs Horn with ease Horn will return to being the unknown mediocre fighter he was before he got very lucky.
