I think that Smackdown will be just fine honestly. 5 Main eventers is perfectly fine, especially with Swagger a first time World Champion. It isn't like he has feuded with all the big names on Smackdown. I expect the main event scene on Smackdown to consist of Swagger, Show, Rey, Punk, and potentially Christian throughout the summer until The Undertaker makes his triumphant return at Summer Slam (I am guessing)
