But they were fictional because the NFL wouldn't let them. Sharks are allegedly the Raiders. NFL also allowed Arliss mentions which was more comedy based, but I agree with
@DaddyFresh Ballers was basically Entourage - dramedy about an NFL agent. Any Given Sunday & Playmakers the focus was 100% on football...and had no intentional comedy. But in support of your point, that was also 20+ years ago. I just doubt the NFL supports authenticity of their behind the scenes activities. Hell, they supported Everybody's All-America (an 80's movie...my favorite football movie), and they supported Little Giants.
