Georges hasn’t been relevant since Hendricks retired him in 2013. Beating a champion in his prime like Usman who is undefeated in the ufc is far more legacy building for Khabib. He knows gsp will be drained and weak at 155, plus his cardio looked very weak in his one fight during the usada era. Basically Khabib is trying to go the easiest route of adding a “big name” to his resume instead of jumping up a weight class to challenge Usman. A bit disappointing that khabib fanboys are eating this potential fight up.
