The AJ Styles, Kaz/Daniels feud is a glimpse into TNA booking at it's worst. One of TNA's biggest set backs as a promotion is that they have trouble trying to sustain lengthy programs, and this feud is a perfect example.
They hit a good stride early on, when they re-ignited the Daniels/AJ feud, but that went on far too long without a pay off, and seemingly went on the back burner for a while before being re-introduced, and having Kaz thrown in to the mix as well.
The biggest misstep was that they waited way too long, and teased for far too long, the twist and 'big reveal' behind why Kaz and Daniels were working together. I think a lot of wrestling fans like to see feuds with a twist, but there comes a point where you just don't want to wait any longer, and the feud becomes pure repetition.
I agree with others have said though, that Kaz and Daniels should move on to the tag team division. Once this their feud with AJ is over, there is really no identity for either of them, especially as singles wrestles. They've been completely redefined as generic heels, and almost enhancement talent for AJ and the likes of Garrett Bischoff, and both are too talented for that.
I hope that AJ's match with Angle at Sacrifice is the start of renewed commitment on the part of TNA to push AJ back in to the main event.
Its ridiculous that they seemingly have no desire to maximize what they have with AJ, a TNA original, that is more over than most of the big name talent they have spent truck loads of money to bring in.
