There were a whopping 23 rule change proposals this year, but only eight passed at this year's NFL Owners Meetings in Phoenix.
Let's take a look:
Instant Replay Isn't Expanding
Of the 23 proposals, 13 were focused on expanding the use of instant replay. Just one of those measures was approved: to review the game clock on the final play of a half or overtime.
The New England Patriots wanted to give coaches the ability to challenge anything, except turnovers and scoring plays, which are already subject to automatic review. Detroit wanted to give coaches the ability to challenge all fouls, while Tennessee's proposal scaled that back to just personal fouls. None were approved.
Tennessee also proposed a rule change seemingly based on its game in Baltimore last season. They wanted to give referees the ability to enforce a foul for an illegal hit against a defenseless receiver when the on-field ruling is reversed during the review process from a catch/fumble to an incomplete pass. Currently, refs can't add fouls based on what they discover upon review.
That is the scenario that played out when Ravens rookie safety Terrence Brooks crushed Titans tight end Delanie Walker, popping the ball out of Walker's grasp. The play was originally ruled a fumble, but overturned to an incomplete pass. The Titans felt it should have been a personal foul upon review. Going forward, refs still won't be able to add fouls after review.
Player Safety Proposals All Pass
The NFL continues to focus on improving player safety.
All five player safety proposals were given the thumbs up, including a resolution that allows a certified athletic trainer at each game to call a medical timeout if a player appears to be disoriented (such as in the case with Patriots receiver Julian Edelman in the Super Bowl).
The Ravens also had a player safety proposal (their only submission) that was approved. It prohibits players from pushing rushing teammates when the other team is punting. That creates excessive force on those trying to block, and can result in more injuries.
"We thought it should be in there to begin with, just because, if you're going to do it with the field goals, why not do it with the punts?" Head Coach John Harbaugh said Tuesday. "It's more of a clean-up type of a proposal."
Extra-Point Discussion Tabled
The traditional extra point remains, for now, but it doesn't seem it will be that way for long.
There were two rule change proposals made in an attempt to make the extra point more exciting and competitive.
One, via New England, was to move extra-point attempts back to the 15-yard line from the 2-yard line, like the NFL experimented with last preseason. Another, via Indianapolis, was to give teams a 50-yard extra-point attempt if they successfully converted on a two-point conversion, which would allow for a possible nine-point touchdown.
After much discussion Wednesday morning, both of those proposals were tabled. There is no clear solution or consensus yet on what to do to make extra points more exciting.
Chairman of the NFL Competition Committee Rich McKay said owners have given his committee 30 days to come up with a recommendation of what to do, and they will vote on the change during May's league meetings.
McKay said there's talk of moving the line of scrimmage from the 2-yard line to the 1 ½-yard line, which would encourage more conversion attempts.
"The alternatives that were discussed today were all over the place, but some were very consistent," McKay said. "It was a very good discussion. There is a clear sentiment that there is a movement to change this year."
Harbaugh said he's fine with moving the extra-point attempt back, but doesn't want to see more two-point conversion attempts.
"I'm OK with it. We have a good kicker," Harbaugh said Tuesday. "If they want to move it back to the 15, it would be an advantage for us.
"I'm definitely opposed to putting the ball at the 1-yard line for the two-point conversion. I think that's just not a smart move. It would be a safety issue. You give a team an opportunity to run a quarterback sneak with the two tackles in there and the backs pushing in from behind, then it's not football anymore. It's rugby. I think that would be the result of it. Plus, you'd have all the pick plays from 1-yard out. That would be the play of choice."
