The BCS statistical rating system determines which teams play in the National
Championship game, and which are eligible to participate in Bowl Championship
Series games. The new system will include three components: the
rankings of the Associated Press media poll, the USA Today/ESPN coaches poll and
a computer average. Each component will count one-third of a team's overall BCS
football advertising ranking. The previous rating system included five components: the AP
and USA Today/ESPN polls, computer rankings, football stats, team record
and a quality free pick. Under the new system, which was unanimously approved
by the 11 Division I-A commissioners, Notre Dame athletic director Kevin White,
the BCS Athletic Director Advisory Committee and the Presidential Oversight
Committee, a team will have a "percentage" score from each of the three
components. These percentages will be averaged to determine a team's BCS
ranking. In the AP and USA Today/ESPN polls, the formula will no longer
average the weekly rank of each team. Instead a team's football stats will be evaluated on the
number of football line voting points it receives in each poll. A team's AP score
will be its points in the poll divided by a possible 1800 voting points. The same formula
will apply to the USA Today/ESPN poll and its 1500 voting points. Six vegas line
computer rankings have been retained for 2004: Jeff Sagarin, whose rankings are
published in USA Today, Anderson football picks Hester, Richard Billingsley, Colley
Matrix, Kenneth Massey and Dr. Peter Wolfe. The New York Times, which
participated in 2003, withdrew a football statistic. A team's highest and lowest
computer ranking will be discarded from figuring a team's computer poll average.
Points will be free picks and calculated by football statisics and
assigned in inverse order of ranking from 1-25. The four remaining computer
scores will be averaged and the total will be calculated as a percentage of 100.
It was apparent to us that just using the average rankings of the polls
was not an adequate comparison of the level of voting support for each team,"
Weiberg said. "A top-ranked team could be one point ahead of the second-ranked
team, or it could be 200 points ahead. Using the actual voting points in the
formula allows for a more accurate ranking in the BCS poll. This is especially
important when there is marginal separation between a No. 2 and No. 3 team."
