If I am not mistaken, that makes Kurt Angle a two time Hall of Famer. Once in TNA and once in WWE.
Same as Sting.
For a while I think TNA was the place to go if you weren't satisfied with WWE. I think they are now in 'rough waters' and probably won't be around much longer. Sadly that will only encourage more crap product from WWE. Also maybe just me, but ever since they started the WWE network and the 9.99 tag, I think the value of their PPVs has gone way down. Seems it's just a thing now and the talent just doesn't quite give it the tug they did before that. As I said though, that's just my opinion.
