Official Review Takeaway: In high-density end zone Hail Mary piles, the ball hits turf at 0:00.28. However, because human acoustic reaction to blow the whistle takes ~220ms and player cluster occlusions create visual delay, the whistle blows when only 0.06s remains or after expiration, leading to the broadcast debate on whether "1 second should be put back on the clock."
