8. Dalton Castle
Dalton Castle is a 'just add water' sensation; His debut in ROH's proving ground tournament was supposed to be a one-off, but fans were chanting 'this is awesome' before he even stepped into the ring! They were blown away by his presence and in your face gimmick, a combination of Liberace and Superstar Billy Graham.
Then he actually got in the ring and displayed tremendous strength, agility and speed. Dalton would end up wearing the ROH world title in a remarkably short time with the company, which is about as high of praise as you can get on the indie scene. Despite numerous injuries, he continues to turn in stellar performances. Could he be on his way to the AEW?
Chances of him joining All Elite Wrestling: 50-50. Dalton's ROH contract is up soon, but there are rumours the WWE is very keen on hiring him, and think he would be insanely popular in NXT. If WWE's offer isn't tempting enough, he could wind up in AEW.
