"The conferences whose champions have a guaranteed annual berth in one of the BCS bowls are subject to review and possible loss of that guaranteed annual berth should the conference champion not have an average ranking of 12 or higher over a four-year period."
This is taken from the "Final" BCS Ranking, which is after the conference championships, but before any bowl games.
Since 1998 the following are the "worst" rankings for a champion from each conference:
1998 - Wisconsin #9 (Ohio St was #4 but was at-large selection to Sugar Bowl, Wisconsin played in Rose Bowl as Big Ten Champ; not sure how this would affect the 4-yr rule).
1999 - Wisconsin #7
2000 - Purdue Not Ranked in Final BCS Top 15. (3-way tie with Michigan & Northwestern, but Purdue got the Rose Bowl bid)
2001 - Illinois #8
This is hard to calculate and I haven't found any information regarding the 1998 situation or how Purdue's unranked status as Big Ten rep to Rose Bowl affects the 12th place average rule. If anyone has a BCS ranking that extends beyond the top 15 published on the BCS website, please share it. It would have taken a BCS ranking of 24 for Purdue in 2000 to give the BIG TEN a 4-yr average of 12 (assuming that Wisc's 98 ranking is used not Ohio State's).
1998 - UCLA #4
1999 - Stanford Not Ranked
2000 - Washington #4
2001 - Oregon #4
Obviously the same situation with the "unranked" team in the equation, but it would have taken a BCS ranking of 36 for Stanford in 1999 to put the PAC TEN's 4-yr average at 12.
2001 - Maryland #10
2002 - Florida State #14
2003 - Florida State #7
2004 - Virginia Tech #8
This gives the ACC a "worst" 4-yr average of 9.75, meaning that a BCS ranking of 19 or worse in 2005 would result in a 12 average for '02-'05 period.
1999 - Alabama #4
2000 - Florida #7
2001 - LSU #13
2002 - Georgia #3
This gives the SEC a "worst" 4-yr average of 6.75 for the period of '99-02.
2001 - Miami #1
2002 - Miami #1
2003 - Miami #9
2004 - Louisville #10 (Louisville's 2004 BCS ranking has been allowed by the BCS to calculate their 4-yr average, rather than Pitt's 21st rank).
This gives the Big East a 4-yr average of 5.25, requiring a 28th place ranking or worse in 2005 to arrive at a 12.
1999 - Nebraska #3
2000 - Oklahoma #1
2001 - Colorado #3
2002 - Oklahoma #7
The "worst" 4-yr period in BCS history for the BIG XII is an average of 3.5 from '99-'02.
2003 - Utah #22
2004 - Utah #6
The MWC would need a future 2-yr average of 10th place in the BCS rankings to garner the 12 average for its champion and an automatic BCS bid.
2003 - Boise State #17
2004 - Boise State #9
The WAC would only need a future 2-yr average of 11th place in the BCS rankings get the 12 needed for an automatic BCS bid.
Can anyone help me with the questions listed above? Any additional thoughts/comments would be helpful as well.
