It always depends on how good he looks winning and how good both men performed. If Spence fought well and Mikey still beat him I would make probably Mikey my number 1 based on that great win combined with an undefeated career full of good wins. Right now I have Spence number 3 PFP and Mikey number 8 PFP and expect Spence to easily knock him out. If I am wrong and Mikey beats Spence in style I will give Mikey credit and raise him way up and possibly to 1st place.
#1
Even if he loses but the fight is competitive I might still move him up the list.
This right here. If it goes 12, Spence loses cred, even if he wins
#1 for me. Five division champ and would have just beat another fellow top 10 P4P fighter who is bigger than him.
Neither Usyk, Loma nor Crawford would have a win on their resume' on this level.
