Well, that's a fair argument, though the situation now is that a small group of the rich get richer, rather than just one or two. But the example I mentioned -- Illinois -- in the 45 seasons before my example, they made 14 NTs: 5 1st rounds, 3 2nds, 3 s16 and 3 e8. They are 84th all-time in winning %, with more losing than winning seasons. If Duke did that, and then in the year 2056 we said, well, they've made the first or second round 5 of the last 6 years, no one would be saying how they'd finally reascended back their original glory of a half-century ago.
Why not finally do away with baseline prestige for schools, but keep it for conferences? It would still maintain the order of the game -- there would never be a world where the Metro constantly dominated the ACC -- but would still allow for gonzagas, while also allowing for the fact than in some worlds, Florida state would, through years of hard work and success, simply be a more desirable destination than Duke? A BCS could never fall below C- still, but which BCS school became an A+ would finally be decided by results and by history, rather than the world's opinion in the RL equivalent of 1960.
