NFL senior vice president of officiating Dean Blandino said the uptick in taunting and unsportsmanlike conduct penalties this season was meant to strengthen the example that the league sets for lower levels of football.

"The bottom line is that there's many, many kids out there that are NFL fans that are playing football," Blandino said in the video, "and they see our athletes and they mimic what they do. We wouldn't want some of these things out on the youth football field. We have a high standard in the NFL, and we're going to maintain that standard."

After the first four weeks of the season, taunting penalties are up by 220 percent compared to the same period in 2015.

Blandino, who says in the video that "sportsmanship and player safety are really the two top priorities in the game today," ran through a series of examples to explain what would and will would be penalized. He says the league is "not trying to legislate emotion out of the game" but wants to eliminate:

• "Anything directed at an opponent"

• "Anything that mimics a violent act ... or weaponry"

• Celebrations that are "sexually suggestive"

• Choreographed celebrations that include more than one teammate, use the ball as a prop or include the player going to the ground.

"If we let this go," Blandino says in the video, "it will continue to build and certain players will continue to try to outdo each other. Then it leads to other things. Then it leads to confrontations. It leads to stomping on logos; it leads to players hitting players for stomping on logos. So we've just got to continue to maintain the standard of sportsmanship and the professionalism that the NFL stands for."

Legal celebrations, Blandino says, include:

• Spiking (as long as it is not directed at an opponent)

• Bowing to the crowd

• Saluting to the ground

• Hugs

Finally, Blandino says: "This may seem crazy, but you can just hand the ball to the official. That's fine, too."
