Ziggler vs Rock sounds alright but CM Punk vs Rock is something that can really draw more interest with Punk being the best heel in wrestling today and his promos along with The Rock's will be stupendous. Not saying Ziggler vs Rock wouldn't be great to see but Punk vs Rock is another dream match that most people have been waiting to see.
Yeah but a waste to have it at RR. It'd be better for WM. Have Rock beat Ziggler at RR for the title, then set up Punk for the win at WM.
