THIS IS WHY I LOVE PRO WRESTLING!
The Miz is one of the best stories in wrestling history. For those who aren't in the know: He was a goof on the Real World who wanted to be in the WWE. He was on their early addition of Tough Enough (their reality "be the next wrestler" show) and didn't win. But he kept at it and ended up getting in the WWE. He started off as an interviewer and, by all accounts, was a total laughingstock in the back who the other wrestlers harassed non-stop.
But he stuck at it and slowly got better and better. He's now arguably the best heel in the WWE and main-evented Wrestlemania.
Along the way, he -- in typical heel fashion -- hired Alex Riley (who was on their NXT show, which was a way to showcase newer talent and led to the original Nexus invasion) as his lackey. Miz had an "I Quit" match against John Cena at the last PPV which was essentially a 2-on-1 match in which their plan to have Cena quit (via a secret recording, which was used in a legendary I Quit match years ago between Mick Foley and The Rock) backfired. Cena rallied and Miz said I Quit as quickly as possible since he's such a chickenshit.
The next night, The Miz wanted a rematch. He did not get it. And of course, this wasn't his fault but it was Riley's. He verbally abused Riley and fired him in the ring. So Riley, who took Miz's abuse for some time, snapped and beat the crap out of his former mentor.
It's also a huge sign of their faith in The Miz. He showed he could hold the title and main event a PPV. But now they're using him to get a newer guy over.
It's just a great, time-honored storyline executed perfectly.
