The NFL pass interference rules have been a source of player and fan consternation for years. I’m old enough to remember when pass interference was rarely called; reserved for egregious instances where every one agreed the defender interfered with the receiver.
Back then borderline interference calls always went to the defender and that was that and everyone kind of accepted it. But in the never-ending push for more offense the league liberalized the rule and over time many borderline calls started going the way of the receiver.
This led to where we were up until January 20th of 2019.
