Every year? Come on. It might be "easy" to do once(which I don't agree with), but look at their last ten years:
1999: 10-3-0
2000: 10-2-0
2001: 8-4-0
2002: 12-1-0
2003: 13-1-0
2004: 11-1-0
2005: 9-4-0
2006: 13-0-0
2007: 10-3-0
2008: 12-1-0
2009: 14-0-0
How many teams beat two BCS bowl teams last year? You've got to take the AQ blinders off. I'm not saying their schedule is as hard as an SEC or Big 12 schedule, or even that they would have as good a record in a tougher conference. But a good team is a good team. If the Dallas Cowboys played in a middle school conference, they'd still be one of the best 10 or so football teams on the planet.
