See, what nobody knows is, is that it is an angle being played out by WWE. What's inside of the briefcase, and Miz doesn't even know this, is a valid WWE title shot contract. A-Ri is going to be a huge, main event face after 'Mania because after Miz is given his time in the spotlight at the "Granddaddy of them all", Riley is going to turn on the Miz. He's going to pull the same thing to the Miz that Miz did to Orton. They're going to have somebody knock Miz out (probably an RKO, but that could change down the road) and in a super swerve, Riley is going to act like he's checking on him but when he's positive Miz is out of it, he's going to use either a new finisher, or Miz' own move (SCF) against him, hand the ref the briefcase, and win the WWE Championship. This will be explained by the fact that the GM had made Miz' title shot w/Orton so the Miz' MITB briefcase was still an active and valid contract, and since he transferred ownership of the briefcase to Riley, that gave him an extension on the duration of the contract, thus allowing Riley to cash in on the MITB briefcase and become the next main event player on Raw.
