For any who don't know/saying that they shouldn't do another Hart Foundation. Smith, Wilson, Neidhart, and Hart were called The Hart Foundation 2.0 in FCW. Even after Hart left they still went with the three remaining members and mainly used them as a tag team with Neidhart being the vallet.
They main reason we haven't seen The Hart Foundation 2.0 main stream is because they had planned on bringing them up for the tag division but DH Smith went to the writers and asked to be apart of the Legacy storyline, screwing over TJ and Nataylia. Writers supposibly haven't decided what to do yet, hence the Tyson Kidd bit we're seeing now.
I always thought having Legacy fight The New Hart Foundation would be great matches but they've screwed that over. They would need Manu and Sim in Legacy to make it work since Randy Orton is to big a wrestler to be fighting new guys like Smith and Wilson.
On topic; Should they give Teddy Hart another shot? Only if they truely plan to put him with the New Hart Foundation and push the group for longtime plans. It's pointless bringing Hart back in just to be a singles wrestler since right now Evan Bourne is the WWEs popular high flyer. And as we've seen WWE would rather have small guys fighting big guys rather than two highfliers fighting it out so there's no point in bringing him in as a heel to face Bourne.
They could bring him in with Hart Foundation 2.0, but if they don't do anything with the group then what would be the point in risking Hart being an idiot?
Personally I think the only way The Hart Foundation 2.0 would work would either a) put DH Smith with Kidd and reform their tag team or b) bring in Hart and either bring back Sim and Manu and have Legacy vs. HF2.0.
Right now I think Legacy is a joke group. It's more "Randy Orton and his students" since all they do is help Orton win. Best thing they could do is have Orton win the belt and then have Priceless win the tag titles and start acting like a group instead of a leader and his bodyguards.
