Well...they aren't too far off from the bushwackers. They did beat the Hart Foundation at WM 7 for the WWF tag belts.  So that puts them a little better than the bushwackers.  They were similar to the 90's tag teams (natural distasters, Head shrinkers, Money Inc, Quebeckers) 
They did win a few tag belts in WCW as well.  They've never been a dominant tag team, but a solid unit (20 years ago) And they haven't been around in about 15 years. They are pretty much useless in TNA.  Its sad to see them there actually.
