Eh, while John Cena vs. Punk definitely had the momentum going into Wrestlemania to make it a spectacular main event match, I think the WWE kind of had their hands tied with the title match. RAW is actually extraordinarily messy right now, and has been for months. Going into The Royal Rumble we had Cena and Punk, Orton and Miz, Lawler and Miz, Lawler and Cole, JoMo and Miz, Cena and Orton, JoMo and Sheamus, Orton and Sheamus, and probably a few other feuds/mini-feuds that I forgot. And then at the Rumble we added Orton-Punk and Cena-Miz to the list. Those are 10 feuds/mini feuds going into Wrestlemania that the WWE needed to untangle into three or four matches.
So arguably the most important place to start is the title picture. Who do you put in? Well, Miz seems like an obvious choice, he's the most hated man in the WWE today. So he needs to wrestle against a face... Orton? Been done too many times. Lawler? Not for Wrestlemania. Besides, Lawler vs. Cole will be for more entertaining and worthwhile watching than Lawler vs. Miz. John Morrison? Tempting, but I don't know if he's ready to main event Wrestlemania. That leaves John Cena.
But Cena is involved with Punk, and the feud is going well. Oh well, we can wrap that up at the Royal Rumble and dump it on Randy. Orton vs. Nexus is something we haven't really seen that much of yet and it could be entertaining. The fans are loving everything Orton does right now, and I would imagine see him RKO multiple Nexus members in a matter of seconds will blow the roof off of the building.
So now we have Cena-Miz, Orton-Nexus, and Lawler-Cole with John Morrison and Sheamus being left over. I personally wouldn't mind seeing them lock up for one more match, but I also wouldn't mind seeing them put into a Money in the Bank ladder match or some sort of small pin elimination Battle Royal with a few of RAW's other top wrestlers.
While John Cena vs. CM Punk is a red hot feud and has the potential to be a wildly entertaining match, I don't fault the WWE for doing what they did. Cena vs. Miz should also be great, and while I don't like Orton, putting him against CM Punk and Nexus should be very entertaining, ESPECIALLY if Punk goes over at Mania.
