What do the letters BCS mean when talking about BCS national championships?

Answer 1

Bowl Championship Series...or if you prefer...Bull Crap System

Answer 2

Bowl Championship Series. And, as we've all seen again this year, it failed miserably. Boise State, the only unbeaten team in Division 1A football, was denied a shot at the national championship. Look at how low they have been ranked at the conclusion of the seaon. Their bowl game against Oklahoma was the only BCS game that was worth watching this season. The Broncos got shafted, AGAIN!
