To be honest Kevin Lee is in no position to talk because he is not a "Championship FIghter" yet whereas Poirier proved himself numerous time and has been grinding that division for years.
I think he finally make amend to his loss to Mcgregor and can move on with the next chapter of his life.

One thing for sure, Khabib has never lost a round in his career, and apparently the same goes for sparring, meaning you gonna need hell of a game plan to defeat The Eagle.
I think Joe Rogan is full of BS when he says Khabib has holes in his stand up game, I was watching the fight with Russians comment so didn't get affected by what he said , and what I was seeing is a clear beatdown, I know people say it was Al Iaquinta strategy to go for a brawl, but to be honest Khabib was so fast on his feet, it felt like someone was spamming the jab button at Mortal Kombat and win!

The other thing is the weight difference between Poirier and Khabib, one was a feather weight, the other one could be a welterweight and wrestle at A.K.A with Daniel Cormier and Cain Velasquez...
