For all the slack the WWE gives to Miz, atleast he never goes around violating the Wellness Policy. I bet if someone is happy it's Miz since it takes the heat off of him for now. Welcome to "Jobville" Randy courtesy of Triple H.
He'll return and it will be like nothing ever happened. He's too valuable to the Smackdown brand, he's arguably the one who brings in the most money on Smackdown and Vince will not punish him any further because of this. Randy will come back in no later than 60 days and will be RKOing people left right and center, I'm afraid.
Of course Orton will be jobbing.....to Sheamus at SummerSlam. It's not going to derail him at all. In fact, he'll be a headliner for SummerSlam and during his time away, WWE can build the tension between Sheamus and Orton.
