I'm late to this thread but that's never stopped me before so here goes. I don't think either RWs or Watkins plays were PI, I read constantly on this board how fans want a agressive cover scheme for this defense. Well guess what this is what playing agressive means you have to play the receiver close and make a play for the ball, in those instances it is by rule incidental contact and not PI, if the defender is obviously only trying to keep the receiver from making the catch when contact occurs then it is PI.
The other thing I want to say about this play is that Brady James's jam on the TE was a key to this play and I hadn't noticed it before. Nice play Mr James nice play.......
