I get really torqued off about all the talk about NRC and this one play.
Go back and watch the play. Don't watch the slow-mo instant replay - watch only the play itself and only at full speed and, oh, only watch it one time. At full speed that is a bang bang play and it is not clear at all that it is DPI - it is unclear enough that I believe the official was not wrong to hold his flag. In fact two of them made the same decision not to throw a flag on a bang bang play that was possibly but not certainly DPI in one of the biggest games of the year. When in doubt, don't throw the flag, especially in a close game in the playoffs.
It is more clear that it is DPI in slow mo, especially if you use the somewhat misleading camera angle that is most often shown where you really can't tell where the ball is relative to the receiver. I am not arguing that it was DPI, just that at full speed it was not that clear that it was.
This rule is going to result in a lot more pass interference flags, a slower game and a duller one.
Making a rule change based on a single instance is how you get bad rules.
