The more I think about what HTK said, the more I think it's realistically the most likely reason this one botched so horribly...
...you bring in a guy who is trying to establish himself as a face, and all of a sudden he's going against the new COO while he's still one of the biggest faces in the company.
Punk had a pretty awesome following against Cena, and that's even with the fact that they CLEARLY brought him back too soon instead of having him randomly appear with the title in the crowds, maybe doing a run-in here or there... but it was just too much too soon. Like, do we not realize we possibly could have had a Punk/Rock match at Royal Rumble for the WWE Championship if WWE would have played their cards right? You could have had Punk literally hold the belt hostage, cause months of chaos and mayhem, and then use The Rock to get a match out of a returning Punk based on Punk's displeasure with Dwayne getting to come in and ME Mania whenever he wants, hell, have Rock put his Mania ME spot on the line... have Cena come in and screw one or the other (Punk outta the title so he can fight Rock for it at Mania or Rock out of it so he can have all the focus on them and the conspiracy for Punk can continue as Trips decides against the stipulation after the fact based on Cena's actions)... I mean, that's just one path. But the buildup to even THAT point would have been awesome because he'd have been dodging Trips the entire time... and Triple H could have had time to establish himself as a heel so that the Punk feud when he was back in the ring could culminate at Mania...
...I still think we're getting some good stuff and expect a lot better to come out of this... but it's hard to deny that they maybe screwed themselves out of the money storyline that would have turned Punk into a true to form superstar and could have sent Triple H and even Cena to new heights and helped establish multiple storylines around main feuds for Mania 28.
