After loading the video onto my computer, I went through the play frame by frame. I used two camera angles and found that there was no contact until 1/6 of a second before the ball arrived. At the end of the play, an official was standing beside the receiver, who went right back to the huddle without the slightest protest (not a word and no body language). It was a bang-bang play in which there was contact a split second before the ball arrived. I could produce many examples of non-calls in that situation. I have seen similar plays discussed during replays in which the announcers said that the officials allow defenders to make contact a split second before the ball arrives. That's not how I would prefer such calls to be made, but they need to be made consistently. The call on that play is consistent with how such plays are typically called. The NFL always has knee jerk reactions, as they have had regarding what constitutes a catch. I wouldn't be surprised if they change the rules next year so that defenders aren't given any margin.
