OR - I think this is misleading data. I know that a lot of coaches feel very strongly that there is too great a talent gap and that mid-majors and low-majors simply can't compete. I don't play D1, so I won't even try to speak to this. However, trying to compare RL conference RPI data to HD RPI data is not a good proof of an issue. The simple reason for this is that many, many BCS schools in HD schedule as many as 8-10 mid- and low-major opponents in their non-conference schedules to maximize both team and conference wins. They are intentionally scheduling these winnable games against programs they don't think have a real shot to beat them. This leads to higher RPIs for the BCS conferences and lower RPIs for the guys getting beat up on by the big boys. In real life BCS teams play primarily other BCS teams and the elite mid-major programs in their non-conference schedules.
You compared to Tark. In the interest of simplicity, I just looked up the top team from the top conference. That, of course, is national champion Georgia Tech. In their non-conference schedule, GT played Creighton, Colgate, N. Illinois, Albany, Loyola, Pepperdine, Grambling State, Chicago State, SE Missouri State, and Mt. St. Mary's. Regardless of how cool Touchdown Mary may have been (it's gone now

), you'll never see Georgia Tech playing Mt. St. Mary's in real life. Furthermore, since ALL of those schools were sim-coached, GT's coach was able to schedule all of it's non-conference games on the road. This is also artificially inflating the school's RPI. In real life on the rare occasions that the big boys DO play a weaker school, they make the weaker school come to them. If anything, top programs in the real world play slightly home-weighted schedules. Top programs in HD routinely play heavily road-weighted non-cons since they don't have to please an actual fan base, don't have to establish reciprocity, and are more concerned with getting high RPI numbers than real programs.
