4. Gunner
Ever since returning about three weeks ago, Mr. Intensity has been on a roll, first laying out Robbie E and Shark Boy without even breaking a sweat and, after being chosen as James Storm's tag team partner for Slammiversary, making former TNA World Champion Austin Aries tap out with his feared Gun Rack submission hold. Although Gunner and Storm failed to make it into the Bound for Glory Series due to a dirty victory by Bad Influence, they are still TNA Tag Team Champions and big names on the Impact Wrestling roster. Gunner has been a part of another big faction in the past, Immortal, where he was endorsed by Ric Flair and won his first and only TNA Television Championship. Along with that, Gunner has just been recently reintroduced to the TNA audience, making him a perfect option for Sting to recruit. He has all the potential in the world and, as a part of the new Main Event Mafia, can get more over with the crowd and be established a force to reckoned with on the broad Impact Wrestling roster.
