The RPI ranking shown below is measure a team's strength of schedule and how a team performs against that
schedule. This index considers whether a team won or lost but not the margin of the victory. More weight
is given to teams playing and winning games on the road.
The PRD index is an excellent indicator of a teams success straight up. It has a positive correlation to
the number of games a team wins. It simply subtracts a team's Defensive Passer Rating (the passer rating
of a teams opponents) from its Offensive Passer Rating.
