For me it breaks down as follows (If I were the guy signing people to the WWE and TNA just folded)
1. AJ Styles - This guy is the future of wrestling. The moves he puts on I've never seen any other wrestler or athlete do in a ring or out of one. He has so much talent, charisma, mic skills, everything that you need to suceed in the business, and no matter how much he trys to be a heel the people always love him. If TNA closed and I didn't sign AJ Styles, it would be a complete failure.
2. Christopher Daniels - Another guy just like AJ (though not as talented IMO) who puts on matches like almost nobody else in the biz, and has been for years now. This guy could easily be the biggest thing in wrestling if given the right character and time to work on it.
3. Samoa Joe - Another one of the greats of this modern era of wrestling, undoubtedly a future legend, this guy is just amazing. I used to think he was overrated, but I've since changed my mind completely, he deserves all the praise he gets and more. This guy can main event any time, any day.
4. Abyss - One of the few real "monsters" left in wrestling in my opinion. This guy is great, and can always put on a good series of matches if given the chance (look at his feud with Sabu, or Sting). Plus, the black hole slam is one of the coolest finishers I've seen in years.
5. Sting - Although the WWE would undoubtedly screw this one up, he atleast deserves a chance in the big one. I know he hates the WWE, but lets say that changed. He would be a great addition to any brand, and could put on great main events with guys like 'Taker. Not to mention that when Foley comes in for his annual visit, the matchs with those two would be INSANE. Does anybody else remember their WCW feud? Falls Count Anywhere=Madness!
6. Christian Cage - Never should've let this guy go, great mic skills, great technical ability,just great all around. Although however, he has never struck me as a main event caliber guy. I picture him more along the IC title hunt, and that's always been my opinion of the guy.
7. Kurt Angle - Forgive me for putting him so far down on this list! Another guy they never should've let go, easily one of the greats of the last 20 years. No explanation really needed as to why to pick this guy back up.
8. Petey Williams - The Canadian Destroyer is just f'n badass, and he'd add greatness to the CW division. This guy is so underrated, people need to pay more attention to him.
And so many more. Throw in Chris Sabin, Jerry Lynn, Rhino, Dudleyz, Roode, Senshi, etc., etc.
