Ryback vs. CM Punk
Yeah, I know Punk vs. Taker, Punk vs. Triple H, Punk vs. Rock are what a lot of fans are talking about, but think about it. Ryback has been chasing Punk but can't seem to put him down. Punk loses the title to Rock at the Rumble, thus freeing Punk up to take on Ryback and give him a match that will solidify Ryback as legit main event and setting him for a post-Mania title hunt. Ryback vs. Cena at Summer Slam would definitely be a big ticket seller.
