Here’s a good example of a good “no-call” that looks like interference from the sideline opposite the camera.
The officials working the sidelines, head linesman and line judge, are often the calling officials along with the back judge in pass interference situations. I worked back judge for several years before moving to referee, and the old adage is true about that position. It’s 95% boredom and 5% shear terror! How often have you seen the team that’s losing throw up a desperation pass hoping for a miracle or a penalty? The result often isn’t cut-and-dried, nor as black-and-white as the zebra’s stripes—it’s a judgment call and it usually rests upon the decision of the back judge.
Here’s an example of an obvious foul. Offensive pass interference carries one of the stiffest penalties in football—15 yards from the previous spot and loss of down.
Next time you think you’ve seen pass interference, remember, it’s a judgment call and the back judge should have the best look. Enjoy the game, and see the ball.
