#1 A working relationship with Cody Rhodes
The Usos' long tenure on the main roster saw them more than once interact with Cody Rhodes. On occasion, they were partners in crime against opposition like The Shield. They also worked as opponents in different incarnations of Rhodes’s team with his half-brother Goldust — all of that besides sharing time in the locker room for many years.
While Rhodes and The Usos aren’t known to be the closest of friends, there’s every reason to think they respect each other. Moreover, their kinship over being talented performers who have often been passed over by WWE make a business partnership to follow a totally logical conclusion.
Rhodes snagging The Usos might not seem like AEW’s biggest acquisition, but introducing the Anoa'i family to AEW could be a deceptively big play, and potentially open the door for other cousins to make their way out of WWE and over to the new AEW fold in time.
