As much of an interesting and (in my eyes) exciting fighter as Jones is, i'd like to see him lose. Solely for the reason that he's been proven to have used PED's. I seriously would be one of his biggest fans otherwise.
But for Khabib, i'd like him to stay undefeated - that is as long as he doesn't fight Georges St-Pierre.
I hope Khabib fights at the very least three more times including the Tony fight at lightweight though.
He's in his absolute prime and i think he has some more fights in him, especially since he doesn't really take any damage in his fights.
