ENGLEWOOD, Colo. -- When some of the NFL’s officials rolled through the Denver Broncos complex during training camp to enlighten the team’s coaches and players on the rules changes for the season as well as the "points of emphasis," the Broncos saw one of their own on the training video shown to every team in the league.

In the portion of the video that discussed centers moving their heads or their hands too much before the snap in an effort to get defensive players to jump offside, it was the Broncos’ Manny Ramirez who was used as the example of what not to do.

And after five offside penalties on Broncos defensive players Sunday, head coach John Fox believes not everybody got the memo, citing some “abrupt’’ movements from Kansas City Chiefs center Rodney Hudson.

Asked Monday for the root of four different defensive players being flagged for five offside penalties in Sunday’s 24-17 Broncos win, Fox said:

"They might have been a little abrupt. [That’s] something we’re, of course, going to turn in. I can’t speak about it, but we’ll turn it in."

One of those penalties, from defensive end Quanterus Smith late in the fourth quarter, negated an interception return for a touchdown by Broncos cornerback Aqib Talib. Fox also didn’t let his own players off the hook, either, as defensive end DeMarcus Ware was flagged twice to go with one penalty each for Smith, Von Miller and Terrance Knighton.

Because of crowd noise at Sports Authority Field at Mile High, the Chiefs used a silent count for much of the game -- "There was no cadence," Fox said.

"After maybe one or two, think we probably should have adjusted a little better," Fox said. "[But] the squatting and turning of the head fairly abruptly, you know, was something that we’ll make sure the league knows about."

Asked about the team viewing the training video this summer, Fox added: "Yeah, something we made people aware of. It didn’t work out so good."

"They had a really good snap count," Ware said. "There’s no excuse, it’s watching the ball. But when you have a lot of movement before the snap of the ball, you get a little antsy."

Last season the Broncos' defense was flagged for five offside penalties all year.

Before the season, officials were told to flag centers under the guidelines that "prior to the snap, any quick, or abrupt movement by any offensive players, or several offensive players in unison, which simulates the start of a play, is a foul."

The league's directive also said among the things to be penalized was to be "a center abruptly lifting or dropping his head not immediately followed by the snap."

In the league’s training video it was Ramirez who was shown quickly dropping his head without snapping the ball.

The NFL made it a point of emphasis given there were 33 neutral zone infractions by defenders flagged in 2005. Last season there were 132. Last year Broncos opponents were flagged seven times for neutral zone infractions and three for being offside.
