Didn't read the whole content but to me, this analysis is incomplete regarding a player's worth in winning games. The running game is not as important as it once was but is still needed and a player's worth should be tailored to a team's need. This argument should be extrapolated to every other position as well. How important is drafting a day 1 vs later round WR, TE, CB, DE, OL on winning games? How important are special teams, turnovers, injuries, weather, etc involved in a game when comparing rushing data? There are too many variables to look at besides just a running back's production and draft position.
