They'd better be relying on a lot more than that.
Cena's champion now; so, there'll be lots more heat in certain storylines. There seems to be one building with him and Ryback and/or Mark Henry (though Henry's ambush of Sheamus on Smackdown may change that).
As for the guy to whom this latest craze is credit, he and Jericho are really building some serious beef.
It should result in some wild match at Extreme Rules.
And with Del Rio still gimpy, who's going to be Ziggler's first major challenger, Orton? Perhaps even Swagger?
Plus, you have this internal friction on Smackdown between Teddy Long and Booker T. Methinks Teddy wants his old job back.
