#2. Changing landscape
In case if you don't know, Fox Sports has recently purchased the rights for Smackdown LIVE. Fox wants Smackdown to be sports oriented rather than just having silly segments. This demand would certainly help Kenny Omega, one of the most proficient professional wrestlers in the world, to rise to the top.
Smackdown is already pushing talents. Mustafa Ali, Andrade Cien Almas, and various others are getting decent or more screentime and opportunities to shine. Omega could easily make use of this scenario. Even on RAW, there is a vacuum in the top of the card.
Seth Rollins and Braun Strowman are the only top faces of the brand, and thus, the red brand could also use him. His versatility and ability to be an effective heel or face would also help him in the cause.
In an era where WWE is struggling with a lack of credible stables, Omega could even be a part of a stable - especially with Karl Anderson and Luke Gallows.
