Officially speaking: Roughing the passer

The NFL is increasingly concerned with protecting quarterbacks.

Sometimes that concern makes it tough for a defensive player to carry out his job aggressively. Sometimes a borderline roughing-the-passer penalty can influence a game's outcome.

When the St. Louis Rams' Oshiomogho Atogwe and Fred Robbins drew roughing-the-passer penalties during a 16-14 defeat at Oakland in Week 2, the plays wound up factoring into the outcome significantly. The foul against Atogwe sustained a Raiders drive to a field goal. The foul against Robbins, which seemed like a borderline call from the Rams' perspective, allowed Oakland to run out the clock.

What if Robbins in particular had known that the referee that day, Tony Corrente, called far more roughing penalties than some of his peers? Might Robbins have backed off instead of giving Raiders quarterback Bruce Gradkowski a little shove? I'll try to ask Robbins Sunday following the Rams' game against Seattle.

It's entirely possible the referees with more roughing calls witnessed more cases of roughing. It's also reasonable to think referees apply slightly different standards when determining whether to call roughing the passer. Crews associated with Corrente and Ed Hochuli call more non-roughing penalties than other referees, so it's no surprise to see them near the top of the list for roughing, too. Al Riveron ranks tied for first in roughing calls and 10th in non-roughing penalties since 2008.

The chart, put together with information provided by Hank Gargiulo of ESPN Stats & Information, shows how many roughing-the-passer penalties each referee's crew has called (including declined penalties) over the last three seasons. Note that Clete Blakeman is a first-year referee. The others listed have worked as referees since at least 2008.
