BCS is like life. It isn't fair, it cannot be made fair, but it still beats the alternative. The shear number of college football teams (more than 500) plus the amount of rest and practice that teams need between games (a week) means that a season followed by a tournament would take too long.
Some in Congress want to change the system. Should we be upset that with all the problems facing the nation that Congress wants to spend time on this? Or should we be glad that this distraction means that Congress will be spending less time screwing up on more important matters?
