Josh McDaniels‘ decision to break his agreement to become the Colts’ next head coach could hypothetically push the NFL to change its hiring rules, as Mike Florio of Pro Football Talk writes. Currently, teams aren’t allowed to formally hire coaches who are still employed by playoff clubs, but that hadn’t been an impediment given that no presumptive head coach had backed out of a reported deal. Had McDaniels been able to be officially offered the Indianapolis job several weeks ago, the Colts may have been aware of his wariness at the time. The NFL discussed a possible hiring rule change in 2017, but tabled the discussion, per Florio.

Here’s more from the 2018 coaching carousel:

• The Jets announced that Jeremy Bates, who was recently promoted to offensive coordinator, will also retain his role as the club’s quarterbacks coach. While Bates will have two jobs, he’ll be able to rely on the expertise of assistant quarterbacks coach Mick Lombardi and longtime NFL offensive coordinator — and new New York offensive line coach/run game coordinator — Rick Dennison. Bates & Co. will likely be working with at least one new signal-caller in 2018, although the Jets are open to re-signing veteran passer Josh McCown.
• Former Patriots assistant Ray “Bubba” Ventrone will be hired as the Colts‘ new special teams coordinator, according to Alex Marvez of the Sporting News. Ventrone, who played for four NFL teams, had been a New England staffer since 2015, but this will be his first run as a coordinator. Indianapolis is also expected to hire ex-Lions defensive backs coach Alan Williams for the same role, per Marvez, while Field Yates of ESPN.com reports (Twitter link) former Buccaneers assistant Dave Borgonzi will become the Colts’ next linebackers coach.
• The Cowboys have finalized their 2017 coaching staff by hiring Doug Colman as their assistant special teams coach, per Todd Archer of ESPN.com. Colman spent the past four seasons in the same role for the cross-state Texans. He’s expected to be the last major hire on Jason Garrett‘s staff after Dallas promoted Keith O’Quinn to ST coordinator and hired Doug Nussmeier as tight ends coach.
• Florida Atlantic University defensive coordinator Chris Kiffin is joining the NFL ranks, as he’s agreed to become the 49ers‘ pass rush specialist, according to Bruce Feldman of Sports Illustrated. Kiffin comes from a long line of NFL coaches, as he’s the brother of Lane Kiffin and the son of Monte Kiffin. In San Francisco, he’ll work with young defenders Arik Armstead, Solomon Thomas, and DeForest Buckner.
• The Giants have announced new head coach Pat Shurmur‘s staff, and the new list of assistants contains several holdovers. Rob Leonard (assistant linebackers), Ryan Roeder (offensive assistant) and Bobby Blick (defensive assistant) will all stick around.
