I'm picking Khabib via early round Rd 4 ref stoppage.
Conor will edge out a close but uneventful round 1(but a round where Rogan and Anik explode in their typical orgasmic ecstasy every time Conor does anything)... Round 2 will be more of the same, but Khabib will push the pace and land a late round TD.... Round 3 Khabib will land a takedown, and really start putting on a beating on Conor... Round 4, a tired and wobbly Conor comes out, gets taken down and beaten until the ref intervenes.... Aaaaaaaaaaaand still.... That's my take.
