I see the QB play differently. I would argue that QB play is as high as it has ever been and that is evidenced by the amount of passing yards, TD's and QB ratings in recent years. I do think there was a drop off in 2017 though. Part of the better QB play are do to rule changes. But I do think the QB play can negatively impact ratings but not because it is shoddy, rather because the great QB's factor into wins and losses too much and more than ever. For instance, a team that had Peyton Manning or Tom Brady or Aaron Rogers is basically guaranteed to with 10-12 games. When Brady is playing Bortles in the championship game Brady wins.....it does not matter how good the Jags played on D for 3 quarter or even that Bortles was efficient and did not make a lot of mistakes. Brady gets the ball when they need points they get points.
