Arians, however, said he hasn't "definitely said yes" to being added to the committee.
According to Adam Schefter of ESPN.com, Cardinals coach Bruce Arians and Broncos executive John Elway have been added to the committee, which sets the agenda for rules changes. Committee chairman Rich McKay had been suspended after the Falcons' fake crowd-noise scandal, but he had been reinstated a year ago.
There are now nine members on the committee. The other members are New York Giants owner John Mara, Dallas Cowboys executive vice president Stephen Jones, Green Bay Packers president Mark Murphy, Baltimore Ravens general manager Ozzie Newsome, Houston Texans general manager Rick Smith, Cincinnati Bengals coach Marvin Lewis, Pittsburgh Steelers coach Mike Tomlin and Los Angeles Rams coach Jeff Fisher.
The league's competition committee is responsible for reviewing "all competitive aspects of the game, including (but not limited to) playing rules, roster regulations, technology, game-day operations and player protection, "as the website puts it".
