75%? You kidding me? When I go to big events, the crowd is almost always north of 95% white.
I went to a UW Football game and looked all around. While the field has 80% colored players, I could hardly find one single african american in the stands.
Money? No, because many teams or sports offer tickets for as little as $5 or $10 to attend and still, no African American support for an event played by 80% afromericans.
I was being kind. They buy the bling and the jerseys though. I see them wear the stuff.........
