Going by resume you cannot rank him. Going by skill and potential he is top 5 just has to kick on now and fight all the elite guys around 135-140 to prove it.
Just think about it, 23 year old Lopez beating Lomachenko the way he did would have been like 23 year old Canelo outboxing Floyd when they fought (I'm not saying that Loma is as good as Floyd but you get the idea). The sky is the limit for Lopez. I say he could become an ATG if he continues improving, since he is no where near his peak.
Top 20, maybe top 15? He's beaten one guy worth mentioning. If he beats the winner of Luke Campbell vs Ryan Garcia then we can start talking about top 10.
he's the man who beat the man, and in some ways, dispelled the legend a lot of people thought loma was despite the salido result. i'm not saying that to downplay loma's ability, he's a terrific fighter, but it's also going to put in context exactly how difficult it is to truly be an undefeated career fighter like floyd was. the salido loss can be called 'lightning striking once', but this fight reinforces that being as versatile as floyd just isn't something that happens very often.
Lopez is easily top ten after last night. He has a better single win than anyone besides maybe Canelo, and a solid KO win over Commey. So Loma is also out of the top ten?
His knockout against Commey was impressive and obviously his win last night was the biggest of the year by FAR. He's the undisputed LW champion now so that has to account for something, it's just top 10 guys usually have a longer body of work on their resumes so that's where the conundrum lies. I'd have no problem putting him between #10-15. All he has to do at this point is defend his kingpin status a few times at 135 lbs and he'll be moving up the P4P ladder quickly.
All night long all ESPN could say was "P4P NUMBER ONE!!!" MY ARSE Tyson Fury is the pound for pound best fighter on the damn planet, maybe you can stick Clenbuterol Canelo behind him. Forget about Crawford, Spence & Loma. Spence is 3rd maybe because he had a fight with pavement and god damn won. Loma & Crawford need to stay in their Top Rank protection unit.
