The point is that after a period of time, if you win enough at ANY school, then the game should gradually change to recognize that school as a powerhouse. On the flip side, if a current or traditional powerhouse falls on hard times and wins 6 games a year for a decade, they should fall off.
It doesnt happen. His point is that with enough effort you should be able to turn a Purdue, WVU or Arizona into a power that the polls recognize and recruits want to go to, but the game doesnt work properly in that regard.
