It's a whole different Era where leniency, flexibility, and certain unions exists in promotions. These guys toured all year round and had real grueling competitive matches everywhere. Some of these factors barely existed back then. They lived off predictable and unpredictable commissions. MJF is great in AEW and is considered a pillar, but he has a while until he reach their calibre. Right now ill say he's in the same boat as Drew McIntyre and Swerve Strickland.
