#2 Marty Scurll
When AEW was announced, many people were saddened that Marty Scurll stayed behind in Ring of Honor, and despite finding new friends in PCO and Brody King, he may reunite with his old friends soon. Nothing has been confirmed, but it's rumoured that Marty's ROH contract is up after the MSG show in April, and if that's the case, then All Elite Wrestling makes perfect sense for The Villain.
As for the story, it makes perfect sense, as Cody replaced him with his new friend MJF with the announcement of AEW, and it looks like Cody has completely moved on from Marty as a friend.
If Marty's contract doesn't expire before May 25th, he clearly can't compete, but it's just a matter of when, not if Marty becomes All Elite, and for the show's sake, we hope that The Villain can compete in Las Vegas.
