There are 19 playing rules proposals on the docket at the NFL Owners Meetings, and seven of those proposed by the NFL Competition Committee were passed.
Rules that have passed include:
Rule: Permanently moves the line of scrimmage for Try kicks to the defensive team's 15-yard line, and allows the defense to return any missed Try.
Rule: Permits the offensive and defensive play callers on the coaching staffs to use the coach-to-player communication system regardless of whether they are on the field or in the coaches' booth.
Rule: Makes all chop blocks illegal.
Rule: Expands the horse collar rule to include when a defender grabs the jersey at the name plate or above and pulls a runner toward the ground.
Rule: Makes it a foul for delay of game when a team attempts to call a timeout when it is not permitted to do so.
Rule: Eliminates the five-yard penalty for an eligible receiver illegally touching a forward pass after being out of bounds and re-establishing himself inbounds, and makes it a loss of down.
Rule: Eliminates multiple spots of enforcement for a double foul after a change of possession.
The Steelers backed the rule to make all chop block illegal.
"We've been advocating that for over 10 years," said General Manager Kevin Colbert. "I think finally enough people realize it shouldn't be part of football. We've always argued that a defender can't protect himself. I think hopefully enough teams recognize that now and we can get that changed."
