I think you’re spot on. In this instance, I was just using the PFF data to support what I’ve seen on the field this year, which is atrocious oline play. I obviously do not have the time to personally review film for every o-line in every game, and understand that PFF has many failings. The only thing I’m confident on is that oline play is significantly below average when compared to the last several years. Why oline play is down could be any number of factors and likely is due to a bunch of different variables.
I’m not sure if that play in the link I posted was an example of an overzealous call…but if that type of football move is now illegal I can see how that would have had a big impact on IOL while not having as much of an impact on tackle play.
Oline penalties are trending up this year vs the last 2/3 years.
