How does is inflate or deflate the QBs numbers though? Let’s say they limit the opponent’s TOP. Would that allow the QB to throw more (because like I said before, Wentz probably has as many or more attempts per game than Dak). The team’s defense does not have a direct impact on the QB’s performance.
No, being ahead in games vs being behind in games definitely affects QBs stats.
Dak and most QBs take more risks when behind on the scoreboard in the 4th quarter leading to more INTs.
The pass rush intensifies when teams have to abandon the run in an attempt to score without using up the clock.
Completion percentage likely goes down in those late game behind on the scoreboard situations. Yards per completion might actually go up.
Attempts will increase in those late game situations because teams pass instead of run; however, if the other team dominated time of possession then overall attempts would be down for the QB with the worse defense.
The effect of a good/bad defense is not going to make a scrub QB have great stats or a great QB have scrub stats but for closely matched QB talents a good/bad defense could definitely cause one to have significantly better stats than the other.
Keep in mind that the effect is doubled when comparing a QB with a good defense to a QB with a bad defense.
Example
QB w/good defense +5%
QB w/bad defense -5%
Total Diff 10%
