WHEN THE FOX broadcast team called out that the officiating crew missed an Eagles false start on a tush push against the Chiefs in Week 2, it promptly ended a blissful summer reprieve from the heated discourse surrounding the play. But the Fox crew didn't mention another potential penalty brewing on the same play.
In the futile fight to stop the tush push in its two-ton tracks, some defenses are adopting an illegal tactic to try to confuse the offensive line into moving early, Eagles players, league sources and even an opponent say. In the NFL rulebook, such a ploy is called disconcerting signals and prompts a 15-yard penalty.
The penalty has not been called since 2017, according to the NFL. An analytics source who studies rules for an NFL club that is not the Eagles said he believed that the Chiefs committed the penalty on the Eagles' tush push on third-and-1 at their own 25-yard-line with 5:29 left in the game.
In the broadcast clip, Eagles quarterback Jalen Hurts shouts his cadence: "Delta set!" followed by a Chiefs defensive player yelling, "Go go!" Hurts again says "Delta set!" but this time it's less clear because there's another voice yelling something else, something that sounds short and fast like Hurts' cadence rhythm but isn't quite distinguishable.
