None of you want to hear it or admit it but, it will happen. CM Punk has risen to be established as one of the major top players in THE 'E right now. Company face or not, there's not very many people ahead of him on the food chain currently. Hell, he's one of only five guys that have their own company provided tour buses for crying out loud. I know the IWC has been crying foul since he's lost his Championship and that actually brings me to my point...
Backstage it's known that CM Punk speaks his mind, doesn't bow down and makes snap decisions. It's been THOROUGHLY documented at this point... hence why I believe that he had to get something after losing the WWE Championship. His run was legendary in the fact that no one else has accomplished it. Stone Cold, The Rock, Bret Hart, Shawn Michaels, John Cena, Randy Orton... none of them in this generation have pulled off what the brass felt that Punk could pull off.
I believe that the only way CM Punk agreed to face The Undertaker was if he were to be the one to end the streak. You have two options, be the man to beat Undertaker or be the man to lose to John Cena or The Rock at Wrestlemania... I'd choose Undertakers streak any day of the week personally. Now, I'm not saying that this is exactly how it's going down backstage but I am saying that Punk got something out of losing that Championship and just a match isn't worth it. Undertaker or not.
CM Punk's accomplishments are insane at this point... and this win will establish fully everything about him. Two time money in the bank winner (Once being at the 25th Anniversary of Wrestlemania.), Won the WWE Championship at the 25th Anniversary of Survivor Series, retained through the 25th Anniversary of Royal Rumble (And 26th.), Was WWE Champion for the 1,000th and 20th Anniversary episodes of RAW, not to mention WHC, ECW, Intercontinental, Tag-Team Champion as well. His list will continue to grow and The Undertaker will be next on that list.
Best. In. The. World.
