We could possibly get one in that scenario, and probably would, but the only guaranteed BCS bids are for #1 and 2 in the standings, and the champions of I think, 6 conferences--SEC, ACC, Big 1, Pac 10, Big 12 and Big East, I believe. LSU did the scenario you described last year and got the BCS bid, even though they didn't win the SEC.
The SMART era CONTINUES!!!!!!
