It would be the absolute end of Saul Alvarez. Think about it, Bivol beats him at 175, then comes to 168, beats him again and strip off all his belts. Canelo would be mentally, irreversibly devastated. Bivol would become the Nemesis of Canelo, a man who would haunt him all his life.
Bivol can beat Canelo at 168, Beterbiev at 175, Ramirez at 175, Vlasov at 175, Buatsi at 175, Smith at 175, Meng at 175 and retire with a strong claim for LHW GOAT. Ideal campaign path for him.
Ahhh you're being pedantic I see. Yes Usyk is now probably consensus P4P number 1. But at the time of the fight between Canelo and Bivol almost everyone had Canelo P4P number 1, and Bivol beat him. So whilst he hasn't beaten the man who is currently P4P number 1, he did beat a man who was P4P number 1 at the time of the fight.
I don't recognize "everyone" as an authority on p4p lists. Especially when "everyone" is a money grubber pushing the cash cow so they can line their pockets and consume themselves in avarice.
You don't have to recognise anything. When I refer to P4P lists, I have never once indicated I'm referring to your P4P list. I don't even know what it is. I'm referring to published lists that can be easily accessed and used for debates.
