This seems to be the focus on this forum the past few days...
So I went and checked the stats of league wide completion percentage, and it is unusually high across the league.
There are 4 QBs right now that are at 70% or higher. They are
Drew Brees - 75%
Kirk Cousins - 71%
Matt Ryan - 70%
Marcus Mariota - 70.3%
...
Dak Prescott - 364 attempts, 66.8%, 2,675 yards, 7.3 rating, 14 TDs to 5 INTs, sacked 45 times, 95.4 rating
PFF has him rated #19
Looking around the league at completion % averages, Dak’s completion % becomes far less impressive.
This is mediocre QB play.
