When they're all often wrong, they just continue on as they never get called on it, and ESPN of course will keep re-running shows about White draft busts from the '80s and '90s while the mind-boggling rate of recent black busts is taboo to mention. It's like the Russiagate witch hunt; there was nothing there but the perps will never admit they were wrong, rather they just keep going, finding new angles and tactics to pursue.
That's the diabolical beauty of the U.S. system -- it gives the illusion of tremendous choice when in reality it's quite rigid with truly contrary views carefully marginalized and/or eliminated altogether.
Your description of the media and their ability to lie about their incorrect assertions over and over reminds me of a favorite quote. This quote was written by an influential man in the early 20th century:
“The more I argued with them, the better I came to know their dialectic.
First they counted on the stupidity of their adversary, and then, when there was no other way out, they themselves simply played stupid. If all this didn't help, they pretended not to understand, or, if challenged, they changed the subject in a hurry, quoted platitudes which, if you accepted them, they immediately related to entirely different matters, and then, if again attacked, gave ground and pretended not to know exactly what you were talking about. Whenever you tried to attack one of these apostles, your hand closed on a jelly-like slime which divided up and poured through your fingers, but in the next moment collected again. But if you really struck one of these fellows so telling a blow that, observed by the audience, he couldn't help but agree, and if you believed that this had taken you at least one step forward, your amazement was great the next day.
The [journalist] had not the slightest recollection of the day before, he rattled off his same old nonsense as though nothing at all had happened, and, if indignantly challenged, affected amazement; he couldn't remember a thing, except that he had proved the correctness of his assertions the previous day.
Sometimes I stood there thunderstruck.
I didn't know what to be more amazed at: the agility of their tongues or their virtuosity at lying. Gradually I began to hate them.”
