4. Chad Gable

In spite of Chad Gable's incredible athletic ability and wrestling acumen, the WWE just doesn't seem sold on him. The failure of his tag team with Shelton Benjamin to get over with the fans is being placed squarely on his shoulders.
American Alpha was split up because WWE believed that Gable was holding Jason Jordan back. He was put into the tag team with Shelton Benjamin because creative allegedly had nothing else to do with either wrestler.

If WWE releases Gable from his contract or fails to re-sign him, he will be met with open arms by ROH or New Japan, who put a higher stock on in-ring action than the WWE. He could also find a home in GFW, or command a high price on the indie circuit.
