Go Army!
Its textbook pi, stop with the over analysis. If the defender blocks the receivers ability to get the ball and NEVER so much as attempts to turn around, its pi.
THis is just straight up not true. You have the head of NFL officiating categorize the PI call as "debatable" and a former long time ref (Jerry Austin I believe) on Mike and Mike saying it WASNT PI. That's enough to conclude there's some subjectivity involved. It was a bad throw that hit the defender in the back, and the receiver never made an attempt to come back for the ball. That's enough right there to be within the rule and picking up the flag, not according to me but according to head of officiating and a former official.
