The coaches and general managers are all out in Arizona hamming it up at some desert spa resort because they are conducting super secret official NFL business. During these spring meetings the NFL competition committee gathers around the camp fire and votes on proposed rule changes. This year there are five of them. This information is from the Los Angeles Chargers official team site.
1.) By Competition Committee; Makes permanent the kickoff rule changes that were implemented during the 2018 season.
At today’s Annual Meeting, owners voted to make permanent the kickoff rule changes that were implemented in 2018. The changes resulted in a 38% reduction in kickoff concussions vs. 2015-17, largely impacted from eliminating wedge blocks. Here's an overview. pic.twitter.com/RISl3DT9Kr— NFL Football Operations (@NFLFootballOps) March 26, 2019
2.) By Competition Committee. It redefines a blindside block as it is a foul if a player initiates a block in which he is moving toward or parallel to his own end line and makes forcible contact to his opponent with his helmet, forearm, or shoulder. It also points out that a player may initiate forcible contact inside the tackle box, but is subject to the crackback and “peel back” block restrictions.
To expand protection of the player being blocked, @NFL owners voted to eliminate blindside blocks. One-third of all concussions on punts were caused by blindside blocks. With the rule change, any forcible contact by the blocker with his head, shoulder or forearm is prohibited. pic.twitter.com/abA2cENnXe— NFL Football Operations (@NFLFootballOps) March 26, 2019
3.) By Competition Committee; Simplifies the application of scrimmage kick rules for missed field goals.
4.) By Competition Committee; Simplifies the application of scrimmage kick rules for missed field goals.
What it does: Scrimmage kick rules apply if a Team B player touches a missed field goal attempt in the end zone before the ball touches the ground, or when either team recovers the ball behind the line of scrimmage.
5.) By Competition Committee; Allows teams to elect to enforce on the succeeding try or on the succeeding free kick an opponent’s personal or unsportsmanlike conduct foul committed during a touchdown.
The league is also going to permit coaches to challenge pass interference penalties for the 2019 season.
Clubs voted to expand replay review to cover offensive and defensive pass interference. The change will be evaluated after one year. Reviews to be initiated by coaches’ challenge unless in the last 2 mins of the half or game (initiated in NY) pic.twitter.com/odMNnb3V69— NFL Football Operations (@NFLFootballOps) March 27, 2019

There you have it. These are the conditions teams will be playing under in 2019.
