Right now I would say Austin Aries. He is consistently having the best matches, and his mic work is untouchable in TNA. The Hogans,Stings, and Hardy's are getting the credit, but the guys that contribute the most are the guys that bust their ass out there. Guys like Aries, Roode, Storm, and Daniels. These guys are the backbone of TNA and without those guys TNA would be unwatchable in imo.
