The flip side of the last point, is Rollins retains over Cena at SummerSlam, and Taker then challenges him for the title. He'd have defeated Brock, and will be a natural face against Rollins' heel persona. This one could easily headline Night Of Champions, ensuring minimal Network subscriber drop-off after SummerSlam. Fans would love to see Rollins get his ass kicked, and Taker going after the belt is fan baiting at its finest. Even better than that, it could main event Hell In A Cell. Additionally, Undertaker has a reputation for hand picking opponents who are great wrestlers. He likes to be made to look good, and he likes mixing it up with WWE's finest. Look no further than when he worked with CM Punk. Rollins is now the best in the world, and it wouldn't be a surprise if Taker wants to get in on that.
