The fine imposed on Giants running back Cam Skattebo for illegal use of the helmet was not a rarity. The flag thrown in real time for it was.

Of eight fines levied by the NFL for use-of-helmet violations in Week 7, only Skattebo’s came with a flag.

The league fined Skattebo $7,073. The seven players fined but not flagged were: Bears cornerback Clark Phillips ($11,550); Broncos safety Brandon Jones ($23,882); Broncos Alex Singleton ($47,662); Lions safety Brian Branch ($23,882); Colts cornerback Cam Taylor-Britt ($7,791); Steelers receiver Brandon Smith ($4,916); and 49ers running back Jordan James ($6,194).

The fines increase as the violations repeat. For Singleton, who was fined $23,882 for illegal use of the helmet, it was the second straight week he was fined.

The officials, for whatever reason, don’t often call penalties for illegal use of the helmet. That’s what made the penalty called on Skattebo so unusual.

The fact that the hit flattened Texans safety M.J. Stewart likely was a factor in the decision to penalize Skattebo. Still, the fact that only one of eight instances resulted in a foul being called underscores the fact that, when it comes to the rule against lowering the helmet and initiating forcible contact against an opponent, it’s something that costs players money far more routinely than it costs their teams field position.
