NFL embraced the ghetto culture back in the nineties with sports media doing the same shortly afterwards. The way sports media started covering college football from recruiting onwards helped bring this to the college level, especially ESPN encouraging recruits to act like clowns in front of the camera. Sanders is absolutely part of the problem, but this is unfortunately filtered down to high school.
The only way I see this genie going back in the bottle is when virtually every rookie coming into the league is uncoachable, talented coaches deciding it‘s not worth it and eventually the inmates are running the asylum. ESPN will love it because of the entertainment value, but lots of fans might not. I never thought I’d get tired of football, but I got sick of the NFL years ago and honestly I’m about done with college as it’s start to circle the toilet.
