True that that storyline reflected what was really going on, but I still think Punk does the business. For jebus sake, if he lay down for Cena, what's a loss to Undertaker going to matter? When it comes down to it, Punk doesn't mind losing as much as his fans mind him losing. Not that the WWE would pay attention to it but they are wringing Punk dry. He'll be a spent force within 3 years if the make him Icarus. Still, doesn't mean it won't happen.
And really, wouldn't working with Undertaker at Wrestlemania be a good enough deal in itself? There's far more interest in an Undertaker match than a WWE or World title match anyway. They're giving Punk the chance to work with the REAL top guy (and everyone knows he is) and that would be reward enough. That's my opinion.
I believe there to be a lot of truth in your last paragraph but I still stand firm that there had to be something more. I don't know, again... we'll never know the true stories but I feel that in Punk's mind maybe just going against Undertaker at 'Mania might not be enough... especially given their last feud...
C M Punk will not end the Streak. I am a Big Punk fan and was pissed that he dropped the title to the Rock. I agree there is not a lot left for Punk except a Rumble win plus the undertaker match will be the Co main event for Wrestlemania which is why he would want it. No shame in losing to the Undertaker as long as the writers do a good build and keep Punk going strong after the PPV.
The main question is how do you use Punk after wrestlemania who should he fued with?
