What would be the best way to put over the Nexus at SummerSlam?

The booking of Team WWE vs. The Nexus at SummerSlam is complicated and multiple issues need to be weighed before a decision is made. The Nexus can't win clean because that would devalue every Raw main eventer, however, Team WWE can't win clean because that would waste the angle they have been building all summer. For it to get over well there needs to be a major swerve. While I think a lot of fans would like to see Cena turn heel, something has to happen. A major return, a major turn, just something has to happen. So to answer your question I do not think it would be a smart move to put The Nexus over clean but hopefully something happens that sparks interest in the product going into the fall.
