#21 Samoa Joe
Samoa Joe. The Samoan Submission Machine. The former Impact Wrestling star and current WWE US Champion is easily one of the best heels in WWE. His feud with AJ Styles was better than anything else on the roster and he showed his range and wrestling ability.
But at age 40, it's highly unlikely Samoa Joe will ever sign with AEW. It's also should be taken into account after years of honing his craft at ROH, TNA/Impact Wrestling and the indies, Samoa Joe has done it all and may want to finish his career at WWE.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
#20 Brock Lesnar
With his UFC career seemingly finished, Brock Lesnar will probably finish his career at WWE. It doesn't make sense to go to another promotion when he knows that Vince McMahon will pay anything to keep him on the WWE Roster. He will always be in the main-event scene and with his recent win at WWE Money in the Bank, he's probably going to be around for a long time.
