#3 Austin Aries
Austin Aries made a huge impact when he arrived in the WWE. He wrestled some amazing matches with the likes of Shinsuke Nakamura, Neville and others. Fans loved him, both in the ring and on the commentary booth. It was shocking to know that he requested his released. He later revealed that the WWE officials had no plans in pushing him further than WWE's Cruiserweight Division and hence he made it the choice.
Austin has been on a roll after getting released. He won a lot of titles on the indie circuit. He made his return to the ROH and Impact Wrestling this year. Austin was perhaps the best thing on 205 live during his stint. It would be great to see him return to the WWE and compete with some of the best performers in the business like Daniel Bryan.
