What NASCAR needs: Shorter races
I like racing. But four hours of racing at one time? Ack.
College basketball clocks in at right about two hours. The NBA? About 2 to two-and-a-half hours. (And all you really need to watch is the fourth quarter anyway.)
Pro football is long -- about three hours and change. College football is roughly the same length. But both of those are deceptive -- on Sundays and Saturdays respectively, there are a hundred games and a thousand highlights, so it seems like it's actually one long game from noon to about midnight. And I love every minute of it.
Major League Baseball manages to squeeze about 10 minutes of quote-unquote action into about 10 hours. Yawn.
And racing? It's loooooong.
