The thing is, TNA haven't been known for bringing in that calibre of wrestler in years have they. Styles, Roode, Joe, all of them were in TNA nearly 15 years ago and WWE's changed a lot since then, moreso than ever since they launched the network.
Agreed. But yet they still, for how utterly shit they are, develop guys who people want to see in WWE. Like EC3, Spud, Lashley, Bully Ray.
See thats the thing though, do they?
EC3, I think is a fair shout as he's shown he has "something". Lashley, is a bit of a meh choice for me and I'd be suprised if people to legit remember who he is.
Spud is perfect for places like TNA or ROH, not to say he couldn't be in WWE, but the WWE audience (or at least the non die-hard fans) have no idea who he is, so it'd be building from the ground up rather than "OH MY, IS IT...IT IS! ITS SPUD!!" sort of stuff in a royal rumble, for example.
And as for Bully Ray, to be honest, I like that character in TNA, but I just don't think it works in the context of WWE. Due to his history there, as Bubba Ray Dudley, he'll alwasy be Bubba Dudley...a tag team wrestler. Not that it's a bad thing, but because very few of the larger audience in WWE will know anything of his run in TNA, you'd again have to basically do the entire storyline again: breaking up from D-von, going singles etc, which I don't think they'd have the time to do, to build him up.
