Who gets the most from his talent?

To me, recruiting is the "oh by the way" part of coaching. I do not really judge a coach by his recruiting, since that is a part of the college game that is distasteful and lends itself most to cheating and unscrupulous methods. I wish one of the experts would do a study to see which D1 coach gets the most from his talent. Surely there must be a way to do that statistically. The recruiting services pretty much rank all the recruits (although their "rankings" at the lower levels are pretty much token marks). So, someone ought to be able to somehow incorporate those rankings with  RPI or Sagarin and see who did the most with what he had. To me, that is the real measure of coaching.
