We're not always going to have a situation where there is only one undefeated team.
Exactly. Sometimes the BCS works quite well. Other times a playoff might make more sense. Neither will be the solution everytime but people push a playoff like it is the best way to do it when it's really no more "fair" than the BCS.
When have you EVER heard NFL fans complain that their system is less fair than the BCS? When have you EVER heard any fan of any other sport complain that their system is less fair than the BCS?
Not only does every other level of football (HS, FCS, NFL) use a playoff to determine their champion, but every other level of every sport, whether it's Little League Baseball or NCAA basketball or NCAA baseball or the World Cup uses a playoff to determine their champion, and not ONCE have I heard a single person complain about the unfairness of the playoff system in those leagues.
The BCS is a crock, and it has made the bowl system worse instead of better. It used to be that all of the New Years Day Bowls had meaning, because #1 didn't play #2. Go back to 1970, when #1 Texas lost in the Cotton Bowl, #2 Ohio State lost in the Rose Bowl, and all of a sudden #3 Nebraska was playing for a National Championship against LSU in the Orange Bowl. Nowadays, only the BCS title game has any real meaning, and it still routinely fails at the one thing it was designed to do better than the old bowl system - determining the national champion.
Well stated.....
