Then if it were up to you, would you at least let them play the #1 or #2 team?
If it were up to me I would have a playoff system but that's not happening any time soon. I'm not a big advocate of the BCS but it has accomplished its mandated goal of matching the #1 and #2 ranked teams each year (while conceding that the designation of those teams are highly subjective).
Without the BCS we would have had the likely scenario of USC v. Mich. in the Rose, OK vs. (most likely) Miami in the Orange and Auburn vs. TX or VA Tech in the Sugar. If we assume that OK loses in this scenario and both USC and Auburn win it would still be unlikely that Auburn would claim a share of the National Championship since USC was ranked #1 by both polls (the only time a #1 team won its bowl game and was jumped in the following poll was my alma mater, Colorado, in 1991--thanks a lot Congressman Osbourne).
Auburn should take a cue from Joe Paterno (who, if IRC, had two undeafted Penn St. teams that were passed over) keep plugging away (and throw in a couple of tougher games outside of your conference).
