Holding up(?) the league: Why Week 1 saw the fewest holding penalties ever called

I don’t need to write that 2020 has not been normal, but I will anyway.

Following in this theme of not normal, there were only 15 offensive holding penalties called in Week 1 of the 2020 NFL season. For comparison, there were 64 called in Week 1 of the 2019 season and 74 called in Week 2 of the 2019 season. Last year it felt like half of those 74 were called against Garett Bolles.
