So frustrating when the announcers constantly say that the back judge needs to first see the play clock turn to zero, then look back at the QB to see if the ball has been snapped and "that's why" the play was not called dead/penalty, because of the time it takes to gaze from the clock to the snap of the ball... like there's some magical 1-2 second grace period. Meanwhile, I'm on my couch and can clearly see the snap happened after the clock hit zero. The rule is the rule. Whatever they have to do to enforce it. Can't snap the ball after the clock hits 0:0.
