I guess I get confused with which calls go to NY and which calls the ref goes under the hood. I thought it was for all challenge flags thrown by coaches were reviewed on the field, but perhaps that is not correct. IMO all reviews should go to a 3rd party and not be handled by officials on the field. There is a natural bias for the refs on the field to justify the call they made.
I agree 100% on the PI - that they should leave the call on the field to stand as 99.99% of the time, because IMO the fact that they let 1 abysmal call dictate that we now have to have the lengthy game stoppages for no reason since they are never going to overturn. Any coach that throws the red flag on PI is wasting a challenge.
Anyway, the fact remains that whenever I see that ass clown Anderson on our game I cringe. I always feel like the games his crew calls are heavy handed and inconsistent.
My understanding, and I could be wrong, is that 100% of reviews involve the on-field official going under the hood. The difference in this case is that scoring plays or turnovers are "automatically" reviewed by the league office. If they deem there's something "worth looking at", they flag the on-field official and he goes under the hood.
So on the INT that involved would looked to me to be pass interference, the league office looked at the play and didn't feel it warranted calling the on-field ref to review it.
On the second INT, which looked to me like the ground aided the catch, that one WAS flagged by the league office, and the ref went under the hood to review. No challenge flag... that's an automatic review.
On the catch/fumble out of bounds, that was challenged by Harbaugh I believe, so that's a under the hood review.
I'm pretty sure this is correct, because I don't recall an instance where the NY review team overturned a call on the field without the head official being in the booth to review. The NY teams job is to flag turnover/scoring plays for review, if it warrants a review, and then assist the on-field ref with the videos and rule discussions.
My problem with the first non-call for the PI was that the league office didn't even feel like it was worth it for the on-field ref to take a look. I think that's a mistake.
