I do blame WWE for some of this, but........:
1. they shouldn't have these brought these guys up unless they were 100% certain that they would do well (sometimes it's not possible to know this for sure, however).
2. maybe WWE did see something in them, then realized that they weren't fitting well with the current talent - there could be lists of reasons.
3. perhaps these guys pissed off the wrong person in upper management. Althought if this case, and even though it seems unfair, in any business you do have to play your cards right. Not everyone can pull a "Punk" and get away with being asn asshole and champion.
I think that sometimes we, as fans, just default to blaming the WWE for all this. When, most likely, that is the case here. But, sometimes guys just mess it up for themselves and don't perform like they should or fit the character well that they claimed they could do. WE can never know the whole story here.
Plus, i thought that these guys were alright in NXT. They always seemed kind of stale to me.
I completely agree, they never showed much character. I didn't get what the big deal about them was.
But, I don't think they pissed anyone off, I think WWE just doesn't know what to do with them.
See Adam Rose, Zach Ryder, Layla, Emma, Summer Rae, and half the roster WWE isn't using.
