Thats a brilliant idea, cut Ranjin Singh... why? Because he isnt on TV? Sure... good reason. But the fact that he is on creative staff means he wont be cut... I would have looked into that one first...
Anyway, here are the guys almost certainly future endeavored, unless the rework tag teams...
JTG (been with the company too long and not even close to being relevant)
Curt Hawkins (tag team guy only)
Goldust (probably more of a retirement)
Bourne (too many mess ups in a short amount of time)
Tyler Rex (Tag team guy or he's out)
Zeke (couldnt get over a bridge)
Striker (no air time, and seems to not be in favor of anyone)
Khali (who cares about the India viewers)
Sin Cara (botchamania 302 will be featuring nothing but this guy)
Barretta (can be used in a tag team)
Regal (also a retirement thing)
Guys who could be cut, but dont need to be:
McGillicutty (needs something new about him)
Ryan (give him a fued)
Riley (put him on tv)
Slater (sucks, but can sell like a pro)
Mahal (X-Pac heat)
First of all, WWE NEEDS jobbers to at least get some of there other talent over such as Brodus Clay when he was squashing everybody in sight. Not to mention, the fact that a few people you have listed on there aren't likely to actually get cut.
Here's some people that will definitely be staying unless WWE says or wants:
Sin Cara- He's legitimately injured, has no reason to be released what so ever. Also, he most likely botches due to him not being used to the WWE life style yet.
Ezekiel Jackson- Not going anywhere, as WWE is going to give him a push and see how he sticks with it on Smackdown programming.
William Regal- If you don't watch NXT on Youtube, which is basically a second version of WWE Superstars, he's actually a commentator on the show. Whether or not they"ll get rid of him or just have him be apart of WWE under a different contract is beyond me.
Goldust- Last time I checked, he's been helping out a bit with some of the Diva matches backstage last time I checked. His re-appearance back in December raised the eyebrows of some people, but he MIGHT go against Cody Rhodes at Wrestlemania 28.
The Great Khail- Although I think the guy needs to hit the gym or just go back to Bollywood, he's not leaving anytime soon. Unless they stop using him to squash other talent or have kiss cam segments, the dude is staying.
Sorry if I went a bit off-topic, I just wanted to clear a few things up on this guy's post.
