Why Miz should be on Team Johnny: Rumors started swirling over the weekend that Miz will officially be added to Team Johnny in the battle of general managers. Logically, that makes the most sense as a way to get him on the card. But it also might be the most boring. WWE did something similar with Drew McIntyre a few years ago with Money in the Bank. He kept losing qualifying matches, and getting another chance, until eventually he got in. Then he was a non-factor. My worry with Miz is, like McIntyre, he'll ultimately get his spot, but nothing will come of it. Besides, I've always thought Alberto Del Rio would be the final member of Team Johnny, and I think that still makes the most sense.
Why the Miz should be on Team Teddy: One wrinkle that no one has really discussed is what if the Miz was part of the general manager tag match, but as a member of Team Teddy? The announcers on Smackdown pointed out that Team Johnny is loaded with former World Champions. They could add another if Del Rio is made part of the team. What about Team Teddy? It's a bunch of mid-card babyfaces. Great Khali is a former champion, so they've got that going for them at least. But who is left for Teddy Long to add? One rumor is Mick Foley. Another, if he's healthy enough, is Rey Mysterio. Mid-card faces like Ezekiel Jackson don't really deserve a spot on the card. Evan Bourne's return from suspension was curtailed by a broken foot.
But the Miz? Making him the lone heel on the side of Team Teddy would be incredibly intriguing. Would he turn and cost Team Teddy the match? Would he help them win and turn face?
WWE did a similar angle with Miz leading up to SummerSlam 2010, where John Cena refused to make him a member of his team versus the Nexus. Instead, Daniel Bryan became the final member, which gave him a huge boost upon his return (you see where he's at now), a feud with Miz and really kickstarted Miz's run to the main event and feud with Cena.
Why the Miz should be left off the official card: Past WrestleMania's have been filled with surprises and segments that weren't part of the official card. For example, I distinctively remember Hulk Hogan showing up to save Eugene from Muhammed Assad at WrestleMania 21, and later that same show, Stone Cold Steve Austin starring on Piper's Pit with Carlito. Those were awesome moments that weren't advertised.
No matter what anyone says, the Miz is still WWE's top heel right now. He's a go-to guy that people love to hate, yet he's still entertaining. He has some credibility as a former world champion, and he does a ton of PR work for WWE because he's a company guy. That's why he was in the main event at Survivor Series. But as a heel, he's not going to add a lot more buys to the PPV. Trust me, if you're not already planning to buy WrestleMania, giving the Miz a throwaway match isn't going to change your mind.
That doesn't mean he can't do something else entertaining to bridge the gap between some of the huge matches on the show. Considering his history with Cena and the Rock dating to last year's WrestleMania, it would make sense for him to stage some sort of sit-in right before the main event, where he says he's high-jacking the show. Obviously, Cena or Rock could take him out, but with elaborate entrances expected for them, it would make more sense for another Superstar to do this. It could be someone like Brodus Clay, or maybe Hall of Famer Edge (could he do one more Spear without risking injury?) or possibly Stone Cold Steve Austin.
I could also envision after the dust settles on Rock and Cena, that Miz hits the ring to "make a statement" and receives an Attitude Adjustment/People's Elbow for his troubles. At the very least, expect some backstage segments with Miz throughout the show leading to an appearance later.
