Based on Wilson’s game-level QBRs in the last three seasons, he has almost 10 more wins than expected. No other player has six more wins than expected during that time.
So how have Wilson and the Seahawks been able to defy the odds? One word: defense.
In the last three seasons, the Seahawks have contributed 4.4 points per game to their net scoring margin on defense, by far the best defensive efficiency in the NFL. Only Alex Smith (2.1) and Andy Dalton (2.1) have had defenses that contributed more than two expected points per game in their starts during that time.
Seattle’s defense has a knack for playing its best when Wilson and the offense are at their worst. Since the start of 2012, Wilson has had 22 games with a QBR below 50, including 15 wins. In those games, Seattle has held its opponents to an average QBR of 34.0 and has had a per-game defensive efficiency of +7.3. In Wilson’s games with an above-average QBR, the Seahawks have allowed a 45.7 average QBR and have had a +2.4 defensive efficiency rating.
