#1 Rusev - Could be a part of RETRIBUTION

Rusev was perhaps the biggest surprise as part of WWE's releases earlier this year. The Bulgarian Brute was touted to become a main eventer, but it did not work out for him for various reasons. Most fans believe that he still has a lot to offer, and following the return of Drake Maverick, many predicted Rusev to also re-join WWE, and perhaps even be a part of RETRIBUTION.
The former United States Champion has not joined any promotion, but AEW's Cody recently spoke about his interest in signing him:
"I think there are two free agents that are on a lot of people's radar, that being Miro -- formerly Rusev-- and Matt Cardona, who was Zack Ryder. Obviously, those free agents should be on any radar. They have literally drawn money. They have TV experience. They have high-profile experience. They have locker room experience. The pros heavily outweigh the cons."
WWE may not want to lose a talented Superstar like Rusev to AEW, and they could try to bring back Rusev, and maybe even lead RETRIBUTION. He certainly has a readymade storyline, having been released by WWE, and coming back to climb up the WWE ladder, this time by unscrupulous means.
