#3 Goldust
Another Superstar that may jump ship to AEW is none other than Goldust himself. Goldust is the brother of Cody, who is currently playing a major role in the new AEW company, so it wouldn't be unlikely at all for Goldust to join him.
The Bizarre One doesn't have an efficient in-ring role in the WWE as he is 49 years old, and there is a huge wave of talents in the company that are emerging, leaving no room for Goldust.
It's clear that the WWE doesn't need him, and that AEW would benefit greatly from having Goldust signed to their company.
With the potential of Goldust joining AEW, there is so much that could be done. You could have Goldust team up with his brother Cody, or the two men could face off in a retirement match for Goldust to give him the send-off that he deserves.
The last time we saw the two brothers face off in a WWE ring, it was a feud that was hugely wasted. Seeing Goldust in AEW could also lead to a potential role as a producer.
