WWE also isn't the underdog compared to real sports. WWE consistently beats all sports besides NFL on cable and has for years. TKO bought WWE for more than the average NFL, NBA, MLB, or NHL team is worth. The NBA came to terms for a $76b rights deal over 11 years. The NBA has a minimum of 1230 events a year.
WWE has signed 4 different $5b+ rights deals in the past 5 years while doing an average of about 450 events per year including Raw/SD/NXT/Main Event/Speed/Level Up/Evolve and house shows, and the tertiary shows are recorded on the same nights as other shows that inflates the number. WM is the biggest sports related money event of the year in the US outside of the Super Bowl and has been for about 15 years straight. They aren't the underdogs. They're invited to NFL/NBA/MLB/NHL and do branded marketing WITH them.
There is not a single fukking thing those billionaire fukkheads can claim to be an underdog at without the exact same delusion the GOP acts like despite having full control of every branch of government and Fox News being the dominant new network in the US for 30 fukking years. Khan saying they're the underdog when it would be like a single NBA team having the biggest event of the year every year that isn't the Super Bowl.
