It's hard to believe that Jack Swagger was once competing at WrestleMania for the World Heavyweight Championship, but the patriotic Superstar appeared to be finally regaining his momentum last year in a feud with Rusev. While he failed to topple the Bulgarian Brute, fans started rooting for Swagger in a big way, and he even got a cool new t-shirt! Unfortunately, he then pretty much disappeared from TV and that momentum Swagger had built up was quickly lost when he started jobbing to Rusev on a regular basis. The US title fits his personality perfectly, so Swagger accepting Cena's challenge is a given. It could be as a face or heel (Zeb Colter has been greatly missed over the past few months), but Swagger coming out and pushing Cena to his limit would be a great way to remind the WWE Universe what he's capable of. If he were to actually beat Cena, a feud between The Real American and the leader of the Cenation would be something new and interesting.
