All fans, of all sports, like to complain about officiating and calls.
In the NFL, with just 16 games, even one lost (or won) to a bad (or iffy) call, can decide playoff spots. So, how do crews do? How often do they flag? Well, with some reseach, we can find out. Here's this seasons NFL crew flag rate.
Interesting note: The NFL has 17 crews, but at most 16 games per week. So, every week, there will be at least one crew off. I will denote off weeks with astericks before the referee's name. Each one indicates one week off. Though two weeks, here's where we are:
John Hussey: 46 (39 accepted)
John Parry: 43 (38 accepted)
Pete Morelli: 40 (35 accepted)
Ron Torbert: 39 (31 accepted)
Jeff Triplette: 38 (28 accepted)
Terry McCauley: 37 (30 accepted)
Walt Anderson: 36 (29 accepted)
Ed Hochuli: 35 (29 accepted)
Craig Wrolstad: 35 (30 accepted)
Gene Steretore: 33 (23 accepted)
Jerome Boger: 32 (30 accepted)
Brad Allen: 31 (23 accepted)
*Tony Corente: 31 (26 accepted)
Clete Blakeman: 30 (29 accepted)
Carl Cheffers: 30 (26 accepted)
Bill Vinovich: 23 (20 accepted)
*Walt Coleman: 21 (17 accepted)
Things that stand out to me:
Tony Corente throws a lot of flags. He threw as many, or more, in 1 game, than 4 other crews threw in two.
Clete Blakeman seems to be the most accurate ref with 29 of his 30 flags being accepted.
On the other hand, Jeff Tripplette and Gene Steretore, each have 10 not accepted. It's 27 percent for Triplette and 31 percent for Steretore. This would seem to me to be in indication that they are making a lot of ticky tack calls that don't actually affect plays, so the team they are benefitting doesn't want the penalty yards. It will be something to keep an eye on and see if the trend continues.
