Khabib vs Poirier
Tony vs Cerrone
Winners fight. Anything else will just make the division more of a mess. I love Gaethje but he was finished twice recently at 155. Pettis called him out, I love it. Both are 2-2 in their last 4, both lost to DP, both won their 2 fights by spectacular finish.
Conor should be nowhere near the belt, & if they make him vs Cowboy the winner will certainly jump Tony. F that! Conor can fight Nate, box for Zuffa, or stay retired for all I care. Just keep him from messing up the division again.
