That is probably what Dustin Poirier is going to do. Khabib Nurmagomedov only completes 46% of his TDs. Khabib is not good at taking opponents down.
However, he will exhaust you fighting him off and trying to get back up. If the fight makes it past 2 rounds, Dustin will be exhausted and punching with pillow fists.
Dustin Poirier was able to go 5 rounds with Max Holloway because he was stronger and bigger than Max, and it was obvious from the first exchange. Max was never able to threaten Dustin. Dustin would also pin Max against the cage in the last minutes of the rounds, in order to get more rest before the end of the round.
I don't think he will get all that extra time to rest against Khabib. To me he looks much bigger than Khabib, and this is why I am giving him a puncher's chance to beat Khabib.
If both fighters are at their very best on fight night, Dustin Poirier will probably lose via exhaustion. LOL
