Are the Young Bucks and Bullet Club the most over non-WWE performers since the end of WCW and ECW? I can't remember seeing t-shirts in the crowd for TNA stars or anyone else for that matter, and in some towns, the number of Bucks/Club t-shirts is quite noticeable on Raw and Smackdown.
Oh for sure. Here at the house shows in Saskatoon, there were Bullet Club / Villain Club / Young Bucks merchandise EVERYWHERE, and we don't even have a Hot Topic! I'm assuming people were buying them online.
