Khabib is one of the best athletes of the whole UFC. He grapples competitive with MWs like Luke Rockhold( he said this himself). I think he could do very well at WW.
C Tyron Woodley -> tossup, Woodley would probably be favorite but we've never seen him against a grappler like Khabib
1 Stephen Thompson -> would obviously get wrestlefucked
2 Robbie Lawler -> very durable fighter, but Khabib wins, Robbie's TDD Isn't that good against wrestlers
3 Demian Maia -> Would look similar to Shields vs Maia, Khabib wins
4 Carlos Condit -> Easy win for The Eagle
5 Donald Cerrone -> Tough fight, Khabib probably takes him down and pounds him, but needs to be careful with Cowboy's crafty ground game
