Since Usman and Colby usually likes to beat up former failed 155ers like Jorge, Burns and post-prime RDA etc. How about the current top 5 of LW division, who would've a better chance in a hypothetical super fight between LW champ and WW champ if one of the top 5 wins the LW belt? C- Oliveira 1- Poirer 2- Gaethje 3- Dariush 4- Chandler 5- Islam I think Oliveira is perfect for 155, not big or not small, he even considers to go back to FW if UFC gives him the chance to fight for FW belt in a super fight, when he says he want FW super fight, obviously, he wouldn't consider a super fight between WW, also even against Chandler he didn't look big, even though he is taller and he isn't thick. He probably wouldn't do good at WW especially not against the Champ Usman, maybe against Colby, since Colby usuallly doesn't do a lot of gnp, Oliveira's submissions might be problem for Colby. Poirer has a good chance, he recently said he was 190 lbs when fighting at FW, he is probably bigger than Khabib, and one of the biggest LWs, he agreed to fight with Nate Diaz at 185 lbs, he isn't afraid of Nate's size, which means he believes he is as big as Nate. Colby also said Poirier was slightly fatter than he was when they working together, although I never thought that means the same size, he is just a little fatter for his size. I think Poirier might have better chance than Jorge, Burns and Oliveira Gaethje, although I never heard Gaethje is big enough to be a WW, he is definitely not a small LW, he is the sparring partner of Usman, and Usman even revealed that Gaethje broke his nose during their sparrings. Perhaps he might not be as successful as Poirier at WW, but still I wouldn't underestimate him either, it would be hard to take down, he has a very good TDD, can kill Usman's or Colby's legs, and can punch hard. It would be definitely hard to put him down. Dariush, he has very good ground game and a KO power, he might be a good match-up even though he might not be mobile enough to control the octagon against a bigger guy, still he needs a 5 rounds fight to prove his cardio, he didn't fight for 5 rounds yet. Chandler is also not a small LW, but the size difference would be too much between Usman, and his chin is not so good, his cardio is not so good at his age, he didn't fight for 5 rounds since 2018, I think Chandler would be the weakest link here. Islam, I think Islam also has a good chance at 170, like Poirier and Gaethje. He is technical, and has very good TDD, it would be a striking match, although Usman would be still favorite, but not sure about Colby match-up.
