I'm a big fan of Dustin , and I'll probably cheer for him, but I think Conor's style is a bit of a challenge for him. Was a big fan of Conor but some of his recent issues have dulled that shine.
That being said...I think conors cardio issues are a little overblown. Not saying it's great but it's not the huge glaring weakness some make it out to be. In the first diaz fight, he punched himself fighting a bit recklessly...in the second one, sure he looked pretty weeded, but lest we not forget he won the 4th round unanimously, threw 322 strikes and defended 6 out of 7 takedowns. Even against Khabib sure he wilted but as we saw against Dustin and Gaethje, that's what Khabibs style is going to do to you.
If Poirer fights more like he did against Holloway it's a more competitive fight, but if he fights like he did against Justin or Hooker I just see him getting hit too much. Poirer has great fundamentals and technical striking but he gets baited into too many firefights where his defense crumbles. Against a measured striker, that could be dangerous.
If Poirer fights measured himself, can work in some of his wrestling and maybe work some time against the fence I think he can win a decision.
I'm a little weary of the cumulative toll of the Gaethje, Alvarez, Holloway, Khabib, Hooker fights.
think Conor wins by KO within 3.
