It seems like Jack Swagger is at a point in his career where he's at a crossroads. It's unlikely that he's going to become a main event level performer, but he's also a considered a good enough performer that he's always going to have a job too. Maybe he has a future as a tag team wrestler. Anything more than that would be a surprise. If he was a part of ECW, he'd probably be booked a lot better just because he's a pretty big guy with a submission wrestler skill set. They have him use the Patriot Lock submission move as a finisher, but other than that he's basic. Heyman probably would use him as more of a submission specialist that had more than one move that could make somebody tap out. Think about how Taz was booked in ECW. He had a "shooter" gimmick where he was presented as a badass. Obviously he's a much shorter guy than Swagger is, but the same philosophy could apply. If you book somebody to be a badass wrestler that knows a lot of submission then that person could beat anybody no matter their size. It's all about the presentation. Swagger would likely be a deadly submission expert in ECW with Heyman booking him. Instead, he's just another guy in WWE.
