#4. Keith Lee betrays Riddle at Elimination Chamber 2021

Keith Lee jumped from the WWE title picture at the start of 2021 to the United States title picture heading into the Elimination Chamber. While Riddle was Bobby Lashley's primary United States title opponent, Keith Lee entered the picture by defeating The King of Bros on RAW.
Bobby Lashley immediately attacked both men. Soon after, it was announced soon after that the United States Championship would be defended at Elimination Chamber 2021 in a Triple Threat match involving Lashley, Riddle, and Lee.
It has all the makings of being a show-stealer despite not being an Elimination Chamber stipulation match. Keith Lee could be the favorite to win, especially since his trajectory since joining WWE's main roster has been upward. If Keith Lee betrayed Riddle, he could potentially join The Hurt Business or go on his own path.
It would be a big character change, but the idea of Keith Lee as a Hurt Business member is exciting to think about. Could it happen at Elimination Chamber 2021?
