Every time TNA brings in a future endeavored talent they lose credibility. They are literally being WWE's bottom feeder when they do that. If they want to become relevant they need to make their own talent. Not a knock on those two guys, they are fine or whatever, but I think if TNA ever wants to move toward a position where people consider them as more than an afterthought they need to generate talent from within.
Actually, that's not even remotely true. Talent is talent, regardless of where it once worked. It's only in this McMahon-run universe fans seem to live in these days that this us v. them mentality perpetuates, because back when wrestling was actually great, there were these things called territories where the same wrestler could work in multiple promotions and never get called idiot terms like "reject" for having left, or been fired from another.
WCW, in fact, built a million dollar company on the "cast offs" of what became their biggest rival, which is hilarious, because you never see people calling Triple H, Mick Foley, Steve Austin, the Undertaker, etc. etc. "WCW rejects". But I digress...
That said, I have no fucking idea who the "Dudebusters" are, so I can't quite comment on whether or not they should be brought in. I literally know nothing of either of these two guys, other than they worked for WWE and were in a tag team with a really stupid name. If they've got talent, personality and name recognition, I'm all for it, otherwise thanks, but no thanks.
