I am perplexed by almost everything people have written. First, business casual is simply a suit minus the jack and tie. Jeans and/or an untucked shirt are not business casual. It is only marginally more comfortable. Jeans are also not that more comfortable than nice formal pants. I don’t wear jeans on a flight.

Exactly. Assuming the numbers presented are correct, then its not even close between the NBA/MLB and the NFL. NBA revenue PER PLAYER is MUCH higher.
