Pac lit up Horn too sometimes but Horn was able to use his physical strength on Pac, ragdolling him, roughing him up, Keith sometimes had success going forward but often times it seemed Pac is the one who moves him around and not the other way.
i think pac took horn lightly for the first half of da fight
that, or he didnt train properly or take him seriously.
horn came for his head, and had no fear or respect for him
similar to how maidana fought floyd
that was a one time thing tho, the blueprint on how to beat pacquaio is already out.
he can be out-boxed once you get his timing down and you don't fight scared. he also needs to respect your power.
crawford and spence would beat him cause they are high level boxers
thurman shoulda beat him too even tho hes not as good as a boxer, but he got out worked
