Another member of the Rams' 2017 offensive coaching staff has departed for a new opportunity, as the Titans named Matt LaFleur their new offensive coordinator. With the move, head coach Sean McVay has promoted offensive line coach Aaron Kromer to run game coordinator and tight ends coach Shane Waldron to pass game coordinator.

"I'm excited for Matt LaFleur and his family as he transitions to the Titans as offensive coordinator," McVay said in a statement. "We're grateful for his contribution to the Rams and our NFC West Championship season last year. As we move to 2018, we are confident in the leadership and guidance of Aaron Kromer and Shane Waldron as they begin their roles as run coordinator and pass coordinator."

While LaFleur was an important piece of the Rams' game planning and installation, he did not call plays in his first year as a coordinator under McVay. With former Texans defensive coordinator Mike Vrabel newly hired as the Titans' head coach, LaFleur will presumably call plays in Tennessee, which amounts to a promotion for the 38 year old.

This is the Rams' second coaching departure for a promotion on offense this offseason. Greg Olson — Los Angles' quarterbacks coach in 2017 — was named Oakland's offensive coordinator earlier this month. L.A. promoted Zac Taylor from assistant wide receivers coach to quarterbacks coach to fill the void. Taylor was the Dolphins' quarterbacks coach from 2013-2015.

"We want to be able to build from within here," McVay said on the subject of assistant coaches earlier this month. "I think we've got a lot of good people that you want to try and do that. I think that's what good organizations do when you just look around the league at kind of the landscape and how things have operated. So that's going to be something that we'll look at if we do end up losing some people."

Kromer and Waldron both joined the Rams' coaching staff for the 2017 season, and their promotions fit that mold. Kromer has spent over 15 years as an offensive line coaching the NFL, and previously held the run game coordinator title for the Saints from 2008-2012. Waldron is entering his fifth NFL season as a coach, having spent time with Washington and New England before joining L.A. last year.

Additionally, Los Angeles recently added to its offensive staff in hiring Jedd Fisch as senior offensive assistant. Fisch has extensive coaching experience in both college and the NFL, most recently serving as the offensive coordinator and quarterbacks coach at UCLA in 2017.
