WWE are always looking to do firsts when it comes to the MITB contract. So perhaps we'll see Rollins getting a regular title shot, then when he loses he immediately cashes it in in a rage.
If the champ gets 'injured', can someone cash it in? Say the champ is delivering a promo with a damaged leg and crutches, then the MITB holder comes out and challenges him. That would be another first, cashing in on an inactive wrestler. Hey maybe they should've done that with Rollins and Bryan, Rollins would've got so much heat.
EDIT: Watched the clip. How does Cena have the authority to bring back The Authority?
