Tonys better standing up. The fight starts standing. Tony will do damage from the bottom when it goes to the ground. He can do damage at any position. It will be close without a doubt for these reasons. Also Tony, imo is more likely to finish Khabib then Khabib finishing Tony, on the ground or the feet. Tony's too tough and his cardio is too good to quit or break. The only way Khabib will win is by smothering Tony for the majority of the fight... Tony has a lot more ways to win.
