6. Seth Rollins
Seth Rollins has defeated nearly every major name in WWE this year, including Sting and John Cena. There's actually not too many names left for him, and at Hell In A Cell he'll be facing Kane. The Kane feud could work out perfectly for a transition to Rollins Undertaker. The Champion would defeat Kane and look to injure him again, only for Undertaker to make the save. Taker challenging for the belt at Survivor Series would be huge for Network subscriptions. It would be the most revered wrestler in history against a cowardly heel champion. That's bound to be a big money draw. And what a story it could end up, with Taker then going on to WrestleMania in his home state as champion.
