TNA is failing because of poor management. Bringing in the Wolves is a fine decision. Who should they bring in? No one? More ex-WWE castoffs? The Rock wouldn't turn around business for TNA, so there's really nothing they can do. TNA has tried booking to the hardcores, to the general public, to everyone. They've tried booking old stars, building new ones... The problem has always been the same: creative.
It is pretty disappointing they Mr #iwantwrestling is giving us more of the same. Granted stories now have more coherence but it still feels like the Russo era.
About the only thing TNA has surpassed WWE on story wise is how to manage the undercard.
Otherwise the quality is basically the same but with a smaller budget.
As for the Wolves, the only guaranteed way to get minuscule ratings boosts are to say 'hey smarks, we've got the American Wolves!!!'.
Would work a lot better than TNA's 500th mystery man/faction being unveiled.
