Interesting article from ESPN. College basketball attendance has been trending down for the last 8 years. There is more parity and fewer truly "great" teams. Personally, I think that the player turnover is getting excessive, making it hard to know the players on the teams from year to year. Loss of continuity makes it hard for fans to care as much.
Maybe it's time for the NCAA to re-examine the one-and-done rule. Let kids declare for the draft right out of HS again, but if they go to college, make them stay 3 years, like baseball does, and maybe we'll see the return of college basketball as a great sport for the fans.
