Teaching the Rams' new offensive system to the group up front will be a process, but one made easier given Kromer and head coach Sean McVay's coaching lineage. It's been well documented how McVay learned under Jon and Jay Gruden. The elder Gruden brother was also the one to give Kromer his start in the NFL, hiring him as an offensive line assistant with the Raiders in 2001.

"Our backgrounds are similar … in that Jon Gruden and Bill Callahan trained me to be an NFL coach right out of college coaching. And Sean McVay, right out of college, was trained by Jon Gruden," Kromer said. "And so we have the same philosophy — although there's tweaks here and there that we're going to work together to find the best answer. And so that's how we felt good and strong about working together."

It's still early in the evaluation process, but the youth and size among the Rams' offensive line stick out to Kromer.

"Being young, they move well because they have young knees, and young hips, and young ankles. So they move well as a group," Kromer said. "They're 310-plus across the board, 320. And you're always looking for the bigger, the faster, the better."

It's no secret Los Angeles finished No. 32 in total offense last year, with issues across the board. And while some of the problems can be attributed to the offensive line, Kromer sees them as collective.

"The group needs to get better," Kromer said. "So how are you going to do that? You're going to try to do your best of coaching the guys you have, maybe finding some guys to help, and just continuing forward. I think it's a process, but I think with Sean McVay's leadership, his ability to communicate the way he does, his competitive greatness — I feel like [that's] going to rub off on this team."
