Chuck Klosterman, writing at Grantland (Bill Simmons' new site), gives a brief take at his favorite rule in all of sports, which he also argues is absurd and irrational--the NBA rule that a team calling a timeout late in the game gets the ball at half court.
I am not sure the rule is irrational. It seems like a deliberate effort to give a trailing team a chance (Klosterman likens it to affirmative action), thus generating excitement. And Klosterman is convinced it works. Nothing irrational about that.
