The Young Bucks
Johnny Gargano
Ricochet
Adam Cole
Prince Devitt
Michael Elgin
I'll play that Leftwich game. WWE readiness/probability of success if they came in tomorrow:
Devitt
Ricochet
Elgin
Bucks
Cole
Gargano
Devitt is already elite compared to anybody, period. He shouldn't even be on this because he isnt an indie guy, he's a major league main event star, and he's over 30. But the OP did say 'abroad', so whatever.
Ricochet is so athletic that he could at least get over as an undercard babyface flyer right now. There is nobody like him. Good look, too.
Elgin is really short, but he's a fucking tank so he's unique enough and big enough to where it isn't a barrier. Would have to tone down his work to the slower & easier on the body WWE standard, but that's nothing a few months in Florida can't fix. He's a white heel Big E Langston. Langston is clearly a face long term.
Bucks heel act could get over because Edge & Christian are distant memories so it's fresh again and new to everybody else. I'd introduce them as faces, have them bump around for The Shield, then turn them for mid card workhorse feuds with Uso's, Matadors, etc.
I'm down on Cole now that I saw how short he was in person. He really lacked presence, too. Comes off waaay better on TV than in real life. They passed on him once already. I was super high on him to the point I thought he could headline one day, but now I don't know.
Gargano is the best promo, by far, of the group. But he's super super tiny, to the point that even in 2013 I think his size is a barrier. YouTube the TV jobs he did a few years ago. He's just a very small framed man. It's a shame, because he's super talented and very driven. I think he'll eventually get a deal, from there, i'm not crazy about his odds of success.
fwiw, my order of "who will end up in WWE" would be much different: Ricochet, Elgin, Gargano, Cole, Bucks, Devitt
I'm told from people I trust that Devitt just isn't all that interested. Not that he couldn't be swayed, but they've tried before and he doesn't seem to want it. He makes a great living, has lots of time off, and is very happy.
I think the first three are locks to be signed at some point, and I think Cole will eventually make it. I'm 50/50 on the Bucks. They have some attitude issues and made enemies there in the past during tryouts. But fuck, the are GOOD.
