TEMPE, Ariz. -- Beside the 13 proposed rule changes and seven proposed bylaw changes presented by the NFL competition committee during a conference call Wednesday, a resolution by the Indianapolis Colts could impact the Arizona Cardinals directly.
The Colts' resolution would give home teams the ability to open a closed roof during halftime. The current rule states that if the roof is closed when the game begins, it cannot be opened. The measure could be voted on next week when the owners gather next week in Orlando, Fla., for the annual league meetings.
There are four stadiums in the NFL with retractable roofs -- University of Phoenix Stadium in Glendale, Ariz., Lucas Oil Stadium in Indianapolis, Reliant Stadium in Houston and AT&T Stadium in Arlington, Texas.
Indianapolis' idea is geared toward the in-game experience, NFL spokesman Greg Aiello said.
"The idea is that if the weather is poor prior to the game and you have the roof closed, and then it clears up and is nice outside and nice to open it for the fans and teams, then you can open it at halftime," Aiello said on Wednesday's conference call. "It is a fan experience, fan engagement proposal for teams with retractable roofs."
The NFL's current policy on retractable roofs states that the home team has to decide whether the roof will be open or closed 90 minutes before kickoff. If the roof is open, and it begins to rain or some sort of hazardous condition develops, the roof is allowed to be closed -- with the exception of the last five minutes of the fourth quarter and overtime.
The roof at University of Phoenix Stadium was open for all three NFC West home games last season, of which Arizona won just one. The Cardinals are 12-10 overall with the roof open since the stadium was built in 2006.
The 13 proposed rule changes include:
Move the kickoff to 40-yard line.
Expand instant replay to include personal fouls.
Eliminate overtime in preseason.
Extend goal posts five additional feet above crossbar.
Move line of scrimmage on an extra point to 25-yard line.
Install fixed cameras on all boundary lines to improve instant replay.
Allow coach to use replay challenges on bigger variety of plays.
Tweak rules on blocks to defenders' legs to include penalties for blockers who roll up on the side of defenders' legs.
Allow game official to contact central command center during replay challenges.
Change rule to allow a clear fumble recovery even if play was blown dead on field.
Take away stopping of clock on sack.
Make pass interference line the line of scrimmage, instead of one yard beyond line of scrimmage to address contact on rub or pick plays.
Change where defensive fouls behind the line of scrimmage are enforced.
