Eliminate overtime in the preseason (proposed by competition committee).. Expand the prohibition on blocking below the waist by offensive and defensive players on scrimmage downs when contact occurs beyond 5 yards on either side of the line of scrimmage and more than 2 yards outside of either offensive tackle (proposed by competition committee).. Allow the replay official and designated members of the officiating department to provide certain objective information to the on-field officials. Basically, the replay official would be allowed to help correct a call before it actually goes to replay (proposed by competition committee, coaches subcommittee, and the Ravens).. Add a loss of down for a second forward pass from behind the line and for a pass thrown after the ball returns behind the line. The Rams almost got burned on a two-pass play by Tom Brady during the 2020 season and they don't want to see it happen again. (Proposed by Rams).. Expand jersey number options for certain positions. If this passes, the rule would allow running backs, linebackers and defensive backs to wear 1 thru 19 and wide receivers could wear any number 1 thru 19 (along with their normal 80 thru 89). This rule has been proposed by the Chiefs.. Implement a spot-and-choose overtime rule. Basically, one team would pick where the ball is spotted in overtime and then the second team would pick whether it wants to play offense or defense.

Instead of an onside kick, this rule would allow a team to try to convert a fourth-and-15 play to retain possession of the ball.
