Saw part of a interview with Matt Hardy and for a change he's seems a little normal.
One of the questions was why tag team wrestling has fallen off the radar:
"We came along during a very special time in the business…the height of the Attitude era. Stone Cold was white-hot and The Rock was a huge megastar. Ratings were great and those guys were selling out arenas everywhere. Management was able to put the top guys on cruise control because they didn’t have to worry, so they had extra time to focus on the tag team division or the women. At the point they’re at now, they’re still scrambling for the white hot guys. John Cena is the face of the company right now but there is no one setting record TV ratings or selling out arenas on a consistent basis. Once they find those one or two top guys that are the franchise players, they can dedicate their attention to tag teams again."
Kind of makes sense.
