#3 Braden Walker aka Chris Harris
Chris Harris was one-half of America's Most Wanted in TNA and he won the Tag Team Championship seven times, six of them being with James Storm. He had everything going for him and looked to be doing really well as a tag team and singles wrestler but then, Braden Walker came along.
When Harris made his debut for WWE in 2008, he was announced as Braden Walker and defeated Armando Alejandro Estrada. But he looked nothing like the svelte, old self.
His WWE career quickly centred around a Knock Knock joke and the catchphrase of "I'm Braden Walker and I'm going to knock your brains out." As bad as that was, fans didn't hear it long as he was released from his contract in less than a month and after just two matches.
