The reason college attendance is down is the same partially the same reason our country is so split politically. You have a large protion of kids that are the pro LGBT and BLM group that think football is toxic mascalinity . (you also have so many kids that would rathe play video games all day). You still have a core (mostly in the blue blood south schools) of kids that do love colege football and are more conservative then people think, Hence the F Joe Biden chants recently.
