Since the UFC Gods have gifted Overeem an immediate title shot if he beats BigFoot, I'd like to see Cormier fight JDS right off the bat. It's the fight that makes the most sense for both fighters.
Someone coming off a win. Winner of Hunt/Struve. Basically one or two pretty winnable fights against people in the upper end of the top ten/fringe. Get a little recognition then title fight.
More than likely what will happen, unfortunately. I'd like to see Frank have two or three more wins on decent competition and then hang it up, would love to see him go out on a positive note. I'm not too interested in seeing him against top 5 guys anymore, with the exception being Barnett.
Everyone seems to miss that JDS is not the champ anymore, Cain is. DC and Cain won't fight and Cormier still wants Mir so that would be a good ufc debut fight.
