Irregardless, if any of the 11 1-A conferences meet the three primary BCS autobid criteria, they will be granted a BCS automatic bid, up to the point that 7 autobid spots are used.
TV market is not necessarily an autobid. TV market or "market", or for that matter, "tradition", "bowl attendance", "TV Households", are not one of the three primary criteria, they are discretionary criteria, meaning if the team meets the three primary criteria, these criteria are not used, if they don't, the BCS 8-person committee, at their discretion, can decide to keep the conference or grant the conference a BCS autobid for any of these reasons or other reasons at their discretion.
The only way Notre Dame is guaranteed a spot from 2006 on, is if they are ranked number 8 or higher in the BCS rankings, according to the criteria. If Notre Dame does not go to a BCS bowl, they are guaranteed $1 million.
Read the criteria here, TS2:
If Notre Dame finishes 6-5 and TCU finishes #6 with a 10-1 record this year, TCU will go to the BCS, and Notre Dame would most likely end up in the Insight Bowl. If Notre Dame finishes 8-3 this year and is ranked #13 or lower, they will not go to a BCS bowl, and if TCU is ranked #6, they will. Not saying they'll get to number 6, but this is hypothetical, but realistic in future years given what happened last year. In 2006, any one of the non-BCS conferences can rank #12 or higher, and they will go. If a BCS autobid conference is ranked below a non-BCS team below #14 or lower, then that conference champ from the non-BCS autobid conference would go to the BCS from years 2006 and beyond. Notre Dame would likely end up in the Gator Bowl with 8 wins and a #13 ranking. Last year Notre Dame had a 5-6 record, and Utah finished 11-0 and went to one of the two at-large spots in the BCS, playing BE champion Pittsburgh. Last year is an example of Notre Dame being excluded from the BCS and a MWC champion being included.
