It seems months ago when we were stressing over the impact of the NFL's 2014 points of emphasis for officiating after an eye-opening preseason. (Ah, yes. It was months ago. Time flies.)

We're a bit more than 70 percent into the season, and with the playoff chase intensifying, I thought it would be worth updating the results and inspecting which officiating crews have reacted most dramatically to the new mandates. The results are in the chart embedded below this post, which includes the first two games of Week 13 (but not Thursday evening's game between the Seattle Seahawks and San Francisco 49ers).

The first point to note is that NFL officials have called more than twice as many illegal contact penalties at this point (111) than they did in all 17 weeks of the 2013 season (54). Recently, they surpassed the 2013 total of defensive holding calls (231); that figure currently stands at 243. (Remember, these numbers from ESPN Stats & Information include accepted, declined and offsetting penalty calls.)

Second, as often is the case, a relatively wide discrepancy exists in how frequently these calls have been made by some crews. The chart shows how many flags each crew has thrown, and I also added a column for defensive pass interference to provide a more complete glimpse into how the crews officiate pass defense overall.

As you can see, John Parry's crew leads the league in defensive holding and illegal contact calls. It's one shy of the lead for defensive pass interference penalties. Its total of 46 "pass defense' calls is more than three times the crew with the lowest frequency of such flags (Walt Coleman). If you have a physical defensive secondary, you're going to much prefer Coleman or Brad Allen (19 total calls) to Parry or Jerome Boger.

Allen's crew, meanwhile, has called the fewest two points of emphasis penalties (seven). It's worth noting this is Allen's first season in the NFL; he was hired from the ACC last offseason.

It's always worth pointing out that some of these trends within crews are impacted by the matchups they are assigned to. But as the season progresses, and crews make their way through the league, you would assume the discrepancies caused by a team's scheme or personnel would normalize.

Note: As always, the bar graph at the top of this post documents the per-game frequency of all penalty calls this season, by crew. Carl Cheffers' crew continues to be the most active at 19.7, with Ed Hochuli's crew ranking second at 18. Per NFL Nation writer Mike Reiss, Hochuli has been assigned the feature matchup of the weekend: the New England Patriots' game at the Green Bay Packers.
