These are probably legit, or close to legit, numbers. I remember when Randy Orton's monthly salary was made public during his divorce, and it turned out he was making around $3.7-3.8 million a year. Him making $4.5 million 7 years after that is definitely in the realm of possibility, which makes all of these other numbers within the realm of possibility.
Bryan probably wasn't considered a "wrestler" or "talent" when this list was made, so him not being included makes sense. I do wonder what Nakamura makes, though.
Oh, and they better get this gender pay disparity taken care of, lest they get raked over the coals (again).
They're sure as fukk not gonna take care of it anytime soon.
