The Running Back Rating equation takes into account both a running back’s performance in previous weeks and the strength of the run defense a RB is going up against to come up with a numerical rating that indicates what sort of game you can expect from players.
RUNNING BACK RATING=
(Average Rushing Yards Per Game + Average Receiving Yards Per Game + (Average TDs Per Game x 50) + (100 yd. games / games played x 50) + (Carries Previous Week x 2.5) + (Opponent's Average Rushing TDs Allowed Per Game x 20) + Opponent's Average Rush Yards Allowed Per Game) / 4
