On a 3rd and 2 play in the AFC game yesterday, the Ravens snapped the ball well after the play clock had expired, but the officials (apparently the back judge is the one with jurisdiction here) made no call and Baltimore duly got its first down, and went on to score the game winning field goal.
Why is this not automated? Basketball's shot clock is accompanied by a bright light and a loud buzzer when it expires. The infamous Jazz-Bulls NBA Finals aside, that generally lets everyone know if a shot happened on time. Surely officials could have an alarm go off and whistle a play dead if it didn't happen on time, rather than this haphazard "is the back judge awake and alert to this" method we have now.
This one's a no-brainer. Football games are smothered in tech help already. Fix it.
