I like Dak and always have.
Youre blind if you dont undetstand how arbritrary PFF stats are.
They have all sorts of made up stuff.
Everyone knows this.
These aren't PFF's infamous player grades. Here they're just taking all pass attempts, then dividing them into "pressured" and "kept clean" to see what the passer rating was. There is some subjectivity involved in what constitutes a pressure, but if you add up all the numbers, they still equal his season totals.
2018 regular season
kept clean 101.0 (17th)
under pressure 87.1 (2nd)
combined (all attempts) 96.9 (13th)
The combined rating is closer to the "kept clean" rating because there were twice as many attempts when kept clean.
But if you think his "pressured" ranking is too high, keep in mind that this would make his "kept clean" ranking too low, since any attempt that PFF my have erroneously put into the "pressured" category would have to go into the "kept clean" category. There's nowhere else to put it. Any attempt that distorts one side favorably, automatically distorts the other side in the opposite direction.
