It wasn't like CBS had to stop the replay of the New England Patriots' third-quarter touchdown pass exactly as the play clock expired, to show that delay of game should have been called.
The play clock expired, a couple more seconds went on and then the Patriots snapped the ball. No penalty was called. A New England threw a touchdown pass on the play.
It wasn't just a missed call. It was missed by at least two seconds. That's hard for the Green Bay Packers to stomach.
It's not the first time this season, and it won't be the last, teams have snapped the ball after the play clock expired, with no penalty called.
