If the goal of the targeting rules are - in the interest of player safety - to 1) eliminate avoidable contact to the head-neck area of opponents who can’t protect themselves from such contact (9-1-4), and 2) eliminate the deliberate use of the helmet to inflict injury on opponents (9-1-3), then this is a good targeting call. Yes, you have to look carefully, but, all of the elements are there. The contact is undeniably to the head of the victim. The victim is a defenseless player. The contact is unquestionably forcible. And, there IS an indicator, albeit a bit subtle. I read all of the comments before I watched the video, so I was expecting something far more incidental than what I saw in the real-time-speed replay. After the pass had clearly been released, I saw the defender continue to move forward with his forehead aimed, and leading, directly at the head of the defenseless player. He could easily have moved his head to his left side (along with the arm with which he was attempting to block the pass) to avoid contact to the passer’s head. Instead, he continued to lead with his head - the indicator - directly into the head of the passer. Oh yeah. He saw what he hit, all right. He took his eyes straight to the eyes of the passer, with no effort to avoid contact to the passer’s head. And the contact was definitely forcible.
As to why it took so long for replay to stop the game, none of us were in the booth, so we can’t authoritatively say. But, as late as the first replay was in this video, the RO probably wasn’t aware of the possibility of targeting before then, at the earliest. I would guess the RO wanted to see a different angle to get a corroborating view before he stopped the game. By then, the ball was ready for play for the next down, and he waited until the absolute last instant to call for the review. Just because the snapper moved the ball, doesn’t mean the ball was officially snapped before the stoppage. It doesn’t look great, but, it happens. And, considering the consequences of a targeting foul, during the review I’m sure the RO wanted to see every possible view - maybe several times - to be sure one of those views didn’t show something to pull him off of the call.
Somebody said “5 minutes.” The video presented doesn’t extend through until the next snap. Once into review, did TV take a break? That happens. Maybe the review didn’t take more than 2 minutes, but TV didn’t come back for the announcement for a while. Add the time while they tended to the victim and got him off the field, yeah that might have been 3, 4, 5 minutes, in total. B, B, B. (You know what that means.) Had it not been called, they’d have screamed that a targeting foul should have been called.
