That's a work 100 percent, the way he is acting throwing middle fingers and physically trying to get at him (the gimmick get at him, if he really wanted to he would been up that ramp NO PROBLEM).
There is no doubt a Seth and Punk match is planned, and Triple H confided into him to be ready. Or Seth knew the rumors were strong and that it might be a possibility and thought about how he would react.
I don't think it's a good look if Seth puts him over like he did with Cody. That has to be frustrating as hell if you're in Rollins shoes and they ask you to do that.
I think Punk's opponents will likely be older guys like Nakamura, Orton, Cena, Balor, AJ Styles, Cody and maybe newer guys like Austin Theory, Dom, Gunther, etc.. I can't see guys like Rollins, Roman, Owens and Zayn working with him and losing. But what do I know
