A lot of people, particularly some ECU and Houston fans a reading a line from this article and misinterpreting it:

Along with the six BCS conference champions, there will be four at-large teams selected for the BCS. But the champions of the five non-BCS conferences -- the Mid-American, Mountain West, Sun Belt, Western Athletic and Conference USA -- are guaranteed a spot if they finish in the top 12 of the final BCS poll.

A non-BCS conference champion also can qualify for an at-large bid if it is ranked in the top 15 in the final BCS poll provided it is ranked ahead of a champion from a BCS conference.

Long said the fifth BCS bowl spot will be open to bidders with the Cotton, Citrus and Peach all being likely contenders.

You WOULD NOT get the Big East's BCS bid. If the champion of C-USA finished ahead of the Big East's champion in the BCS standings they WOULDN'T get the at-large bid. If the C-USA champion finished ahead of the Big East, or SEC champion or something they would qualify for an at-large that. That is another qualification. Originally, the only way a non-BCS school could qualify for a BCS bid is to finish in the Top 12, a Top 6 spot guaranteed a spot. Now, not only do you have those qualification, you have a new qualification. If, say West Virginia wins the Big East is ranked #15 and Memphis wins C-USA and is ranked #14 then Memphis would qualify for an at-large spot, they would not take one of the Big Six conferences' at-large bid. Some people think that if their conference champion finishes ahead of the Big East's champion or a "Big Six" conference's champion they would "steal" the Big East's or that conferences BCS bid, that is incorrect. Also, keep in mind, ranking in the Top 12 every year doesn't mean a Top 12 ranking EVERY year. Example, say West Virginia finishes #10 in the BCS rankings this year, which is possible. Then, all a Big East team would have to do is finish #14 next year, and the Big East would average a Top 12 ranking for 2 years.
