#6 The Hardy Boyz
It's only fitting that Matt and Jeff Hardy return home. The Hardys revolutionised tag team wrestling, with the evolution of the TLC match and other various extreme based gimmick matches. Both Hardys have had a fantastic run in TNA and continue to sit at the top of the rankings within the company, most recently winning the TNA tag team championships against Decay for a second reign.
Matt and Jeff are 39 and 42 years old, respectively. While they continue to compete at a high level, it's important to note that the industry is flooded with a new era of great, young talent, which increasingly puts pressure on the veterans to push the limits in order to keep a job. With that in mind, The Hardys may only have a few good years remaining, so if there is indeed to be a WWE homecoming, it needs to happen sooner, rather than later.
