NFL announces 15 rule proposals to be voted on by owners

The NFL announced 15 rule proposals on Thursday that will be voted on by owners next week.

The league's competition committee and various teams sent in the proposals, which include banning the leaping block attempt on field goals, and changing the challenge flag and replay review processes.

The Philadelphia Eagles, Washington Redskins, Seattle Seahawks, and Buffalo Bills were the only teams to submit changes that made the proposal list.

Many of the proposals have been brought to the owners' attention before, though there are a few new issues that were raised this offseason.

The banning of the "leaper" is the most notable, as several teams, including the Denver Broncos, New England Patriots, and Seahawks, have been sending a player to jump over the long snapper on field-goal attempts. The purpose of banning this act is to avoid injuries, as the leaping player is susceptible to being tripped and landing on their head or neck.

Another notable proposal is to extend the placing of the ball at the 25-yard line after a touchback by one year. The league passed the rule last offseason on the provision that it would be used on a one-year trial basis, but the competition committee is recommending another season to determine what the best move is.

After the San Francisco 49ers used intentional holding to deny the New Orleans Saints a shot at the end zone in Week 9, the committee responded by proposing an unsportsmanlike penalty to any team who commits multiple fouls in an attempt to manipulate the clock.

The Redskins, meanwhile, asked for teams to have the ability to opt out of color rush uniforms.

Here's the full list of proposals:

1. By Philadelphia; Gives additional protections for long snappers on kick plays.

2. By Philadelphia; Prohibits the "leaper" block attempt on field goal and extra point plays.

3. By Philadelphia; Expands the “crown of helmet” foul to include “hairline” part of helmet.

4. By Philadelphia; Amends the challenge system by granting a third challenge if a club is successful on at least one of its initial two challenges, and expands reviewable plays outside of two minutes of each half.

5. By Washington; Eliminates the limit of three total challenges per team per game and eliminates the requirement that a team be successful on each of its first two challenges in order to be awarded a third challenge.

6. By Washington; Moves the line of scrimmage to the 20-yard line for any touchback where the free kick travels through the uprights.

7. By Buffalo and Seattle; Permits a coach to challenge any officials’ decision except scoring plays and turnovers.

8. By Competition Committee; Makes permanent the rule that disqualifies a player who is penalized twice in one game for certain types of unsportsmanlike conduct fouls.

9. By Competition Committee; Changes the spot of the next snap after a touchback resulting from a free kick to the 25-yard line for one year only.

10. By Competition Committee; Reduces the length of preseason and regular season overtime periods to 10 minutes.

11. By Competition Committee; Gives a receiver running a pass route defenseless player protection.

12. By Competition Committee; Makes crackback blocks prohibited by a backfield player who is in motion, even if he is not more than two yards outside the tackle when the ball is snapped.

13. By Competition Committee; Replaces the sideline replay monitor with a hand-held device and authorizes designated members of the Officiating department to make the final decision on replay reviews.

14. By Competition Committee; Makes it Unsportsmanlike Conduct to commit multiple fouls during the same down designed to manipulate the game clock.

15. By Competition Committee; Makes actions to conserve time illegal after the two-minute warning of either half.
