Alex Riley has his pre-show gig, they need him.
Eva Marie makes the company money through Total Divas, like her as a wrestler or not, she has value.
Jason Albert is a trainer at the Dev Center, has value.
Justin Gabriel is doing nothing and will likely never be called up to the roster, so fair enough.
Rosa Mendes is shitty, but on Total Divas, which is making the company money.
Scott Stanford does promo's for international shows and what not, is likely making the company money too.
Tamina Snuka is injured right now, so even if they could, they wouldn't fire an injured person.
Seriously though, I know the go-to releases for a company with over 800 employees is the ones you actually know from TV, but in the end, they are the companies bread and butter, they are the sole reason the company even exists, no matter how shit you might find them, if you're gonna let people go it makes much more sense to fire one of the assistants of the videopackage department than a wrestler.
