Punk needs to win plain and simple tbh. He has looked like shit this entire feud with the exception of Smackdown last night. Rey really didn't chop off all that much honestly. I could see Rey losing at Extreme Rules. Punk winning means that the feud is at 1-1 and they could use whatever the fuck the next PPV is for the blowoff match. Likely ending up being a LMS match, the only match that the WWE seems to use to end a feud.
