DEFINITIONS:

Quarterbacks are ranked according to DPAR, or Defense-adjusted Points Above Replacement. This number represents the total number of points scored due to plays where this QB passed or carried the ball, compared to a replacement-level QB in the same game situations.

The other statistic given is DVOA, or Defense-adjusted Value Over Average. This number represents value, per play, over an average QB in the same game situations. The more positive the DVOA rating, the better the player's performance.

The simple version: DPAR means a quarterback with more total value. DVOA means a quarterback with more value per play.
