Re: What should have happened
Ryback should've gone down to the ring after the match and put him in the Ankle Lock (or other appropriate submission). Would've been a better way to end the show and actually get some heat on him rather than The Shield. Better yet they should just have Ryback work over Cena's ankle/heel over the next few weeks then beat him at ER with that move.
I can't remember exactly what they said Cena's injury was but it was something to do with his heel or ankle I think
