Punk was awful for the last few years, and AJ was never good. So please no to both of them
Punk was best under his straight edge cult run and AJ was her best with Daniel Bryan. Everything after that point was sloppy. They both had good moments but they didn't remain consistently good. Not entirely their faults, we all know how booking and writing goes with the WWE.
I do, however, blame Punk for ruining Nexus.
