Let's not forget that prior to the feud randomly switching to Orton, Punk had gone over Cena THREE times. Not including taking the final pin at EC, he was 3-0 against the face of the company in singles competition. IMO, he should have gone over Orton at WM, and failing that, the match on Raw. Sunday's match was the blow-off, and Punk winning--no matter how much I wanted him to--wouldn't have been sensible booking. Rarely ever does a guy who has won two matches lose the third, especially when he's debuting as the top face on a new brand. Bottom line: he's not getting buried. I dislike that he has been saddled with the inferior Nexus; I dislike that they couldn't decide whom he was feuding with; I dislike that he hasn't won a match against Orton, especially in a revenge storyline where the motive is justified. Buried, though? Not at all.
I don't buy the "he's straight edge so he won't take pain pills that he would benefit from" argument. As someone who IS straight edge, I can tell you that the issue is with drug abuse and recreational and unnecessary drug use. If there is a medication that he could legitimately benefit from, for pain or anything else, I'm sure that being straight edge doesn't mean he rejects it on principle. If he doesn't think he needs it, that's a choice he's making with respect to his own body. I can't speak for Punk though, and will acknowledge that aside from not drinking, smoking or engaging in illicit substances, there are different views on what being straight edge actually means.
If he wants time off, and that's the hangup, he'll take time off and may very well be using his position as leverage. If he dislikes the recent trend of guys randomly showing up and winning titles while he's got no direction, I can't blame him. It isn't out of the question that they say, "We'll give you a run with the title if you re-sign," in order to coerce him into staying. Tonight's loss notwithstanding, though, I'm guessing Miz gets the belt back. It's a wait-and-see situation right now, and none of us actually have any idea what Punk or WWE are thinking or talking about. Regardless, I wouldn't worry about it right now. Admittedly, if Punk does leave, I'll be gutted.
