Detractors of the current system say major college football is missing the boat by not capitalizing on the excitement generated by similar post-season tournaments in college sports while others claim the system simply isn't fair because a true champion can only be determined on the field.
Pro-BCS factions rest their arguments on the college football tradition the bowl games represent, along with the increased emphasis the lack of a playoff system puts on the regular season.
Before the 2004 season, the BCS formula was modified to eliminate team record, strength of schedule and quality wins from the equation, while human opinion was given more weight. In the new system, the Associated Press writers' poll, the coaches' poll, and a combination of computer rankings each count for one-third of a team's overall BCS ranking. The human polls now count for two-thirds of the formula, compared with one-quarter previously.
The BCS formula for 2005-06 season remained the same as during the 04-05 season, except that the Harris Interactive College Football Poll replaced the AP poll.
The BCS was established in 1998 to help determine the national champion for college football while maintaining a bowl system that's nearly 100 years old. Six conferences, including the Big Ten, Pac-10, ACC, Big East, Big 12 and SEC committed their champions to play under the this system.
Before the 2004 season, Conference USA, along with the Sun Belt, Mid-American, Mountain West and Western Athletic conferences joined the BCS.
