Punk straight up buried Darby, kicked out of his finisher and went over him clean with no followup at all. Punk tried to basically shoehorn out Sting, who is legitimately a mentor to Darby when the cameras are off, to try and latch on to the mad pussy that throws itself his way. Punk also got hurt doing really basic shit, twice, then vacated the belt, twice. Even if the media scrum shit did not happen he still fucked everything up just by making the title into a hot potato. Look at the shit Darby does in his free time, much less how he wrestles, then realize that he puts up with being hurt a lot. Imagine being a guy who can tank being thrown off a ladder to take a flatback bump on steel chairs and still work a match and having to put over a guy who breaks his foot and has to be off for six months because he jumped into the fucking crowd.
Also Punk is fake straightedge. Dude takes xanax, ambien, painkillers, all of that shit. His version of straightedge is more like "i don't drink or smoke pot" or "i can pass a drug test because i have a scrip for all of the stuff i take" but he still tries to work people in the back like he is a super hardliner. Meanwhile Darby actually does not do drugs, at all. Not even non-narcotic stuff. But besides having DRUG FREE tattooed on his hands it's not something that comes up very often and if you ask him he will just say "yeah i just like to stay clean" without going on some kind of big spiel about it.
