3. AEW signed Miro (Rusev) in 2020.
Going by the name Rusev in WWE before signing with AEW as Miro, the Bulgarian wrestler had quite the hot and cold run. Rusev never quite made it past the midcard, and despite having his moments didn't reach his full potential.
His brutal wrestling style was noticeably good. Other than that his character was stale, even after a drastic appearance change.
After an out-of-left-field love triangle feud involving his real-life wife Lana, Rusev was released from WWE. Few fans knew what would be next for him.
Fast forward to September 9th, 2020. Miro debuted on AEW with a new look and a refreshed persona. Miro would dominate the roster for months. Eventually culminating in a win against Darby Allin for the TNT championship.
Soon after Miro would become the Redeemer, a diabolical persona that encorporated religion into his wrestling. After a period of being undefeated, Miro would finally see his first singles loss against Sammy Guevarra.
Following losing the TNT championship to Guevarra, Miro took some time away. It wasn't until he was recently given Jon Moxley's spot in the AEW World Championship tournament that he made his return. His next match will be the finals of the tournament, where he'll face The American Dragon, Bryan Danielson at AEW Full-Gear.
3. AEW could sign Keith Lee
Saying Keith Lee was a fan favorite in NXT would be an understatement. Lee came at a time just as the next top stars were transitioning over to the main roster.
His wrestling persona stood out the most, but his grit and determination ended up being what fans loved.
Lee was the only wrestler to hold both the NXT Men's Championship as well as the NXT North American Championship. Lee unseated both Undisputed Era members, Adam Cole and Roderick Strong to end up holding both titles.
Lee vacated the North American Championship, before eventually losing his NXT title to Karrion Kross. After this, Lee would be called up to the main roster.
His time on the main roster was lacking, apparently not being exactly what Vince McMahon wanted in his wrestlers. Eventually Lee would be released after a gimmick change.
Lee's time in NXT granted him with quite a fan following, and as such he'd make a great inclusion to AEW. AEW is filled with villains and could use an underdog with the fans behind him.
