7. Jack Swagger
In 2010, Jack Swagger won the Money in the Bank match at
Wrestlemania 26 and then became SmackDown's World Heavyweight Champion.
Sure, he had an incredibly crappy title reign that didn't last long and was marred by bad booking, but at least he was relevant on the blue brand.
Aside from a few flashes--such as his brief tag team run with Dolph Ziggler--Swagger has done next to nothing on Raw, even losing to the laughingstock of the WWE, Santino Marella, recently.
Swagger deserves better than that.
Outside of maybe Sheamus, you'd be hard pressed to find a man of Swagger's size who has both the wrestling ability and athleticism that he does.
At the very least, he should be an upper mid-carder. But he certainly has the potential to wrestle for World titles.
That won't happen on Raw, though.
