Wow, I am absolutely shocked at how many people think that all of those were pass interference. I do remember one clear one on Williams that was missed. However, that sort of jostling happens on just about every long ball. The two called on Williams in the end zone should not have been called as well as at least two called on Ravens defenders. The first time Williams was called in the end zone he never impeded the receivers run, never slowed him down, and played the ball when it came in getting a piece of it. The second time he was called in the end zone both the receiver and Williams were jockying for position, so if you're going to be nit picky it's interference on both. I also thought the offensive pass interference called on Mason was harsh.
Simply put, that was the tightest I have ever seen pass interference called, in the NFL or otherwise. At a certain point it just gets ridiculous. Every little contact should not be pass interference. Otherwise, we might as well just have a game where everyone chucks it deep and hope you get a call. Hell, while we're at it we might as well train our receivers to start diving like this is soccer to draw pass interference calls. Let the defense play.
