It didn’t take long for the Los Angeles Rams’ depth to be tested this season. They were forced to play several backups in their opener against the Detroit Lions on Sunday night, including three along the offensive line alone.

Injuries have already hit this team hard and Sean McVay has done a good job of adjusting on both sides of the ball. They were without their starting left tackle, backup left tackle and starting right tackle, as well as their starting left guard, cornerback and wide receiver at certain points in the game.

Although the Rams didn’t beat the Lions, they did bring Detroit to the brink with an overtime loss.

Below is how playing time is split on both sides of the ball, with notes on each position group, including running back, where Kyren Williams is still clearly the best option.

Attack

Only five players on offense played every snap, with only three linemen. That’s because Joe Noteboom and Steve Avila both suffered injuries and had to leave the game, as did Puka Nacua. Noteboom played 27 snaps, Nacua played 25 and Avila played 37.

In Noteboom’s place, AJ Arcuri played 65% of the snaps. Beaux Limmer replaced Avila and played 53%, and Tyler Johnson was promoted to a more prominent role with a 65% snap share.

At running back, it’s clear who is still the starter: Kyren Williams. He played 71 of a possible 78 snaps, with Ronnie Rivers playing the other seven. Blake Corum, interestingly, did not play.

Colby Parkinson was the best tight end throughout the offseason, but after one week he has firmly cemented that role. He has played 88% of the snaps, compared to 8% for Davis Allen and 4% for Hunter Long.

Despite Nacua missing most of the game, Tutu Atwell was still a complete non-factor. He played just six snaps and was never targeted, and now sits fifth on the depth chart. Jordan Whittington played just two snaps and would have scored a touchdown on a jet sweep if not for a holding penalty.

Defense

It was a similarly small rotation of players on defense for the Rams. Only 12 players were on the field for more than half of the defensive snaps, with only 13 players overall playing at least 11 snaps in the loss.

Quentin Lake, Troy Reeder, Tre’Davious White and Kamren Curl were the only four players on the field for all 61 defensive plays. Sean McVay didn’t say who was wearing the green dot as a signal-caller, but based on photos from the game, it was Reeder who relayed Chris Shula’s calls to the rest of the defense.

Christian Rozeboom played significantly more than expected, staying on the field 74 percent of the time. That’s partly because the Rams relied on just two cornerbacks: White and Cobie Durant. Lake was the nickel defender, and John Johnson was on the field 62 percent of the time as a deep safety next to Curl.

Jared Verse and Braden Fiske both played significant snaps in their debuts. Fiske was there 77% of the time and Verse played 70%, so they didn’t get off the field much. Michael Hoecht was the only other edge rusher on the rotation, playing 49% of the snaps.

Kobie Turner’s stamina was excellent for a defensive lineman, playing 92% of the snaps up front. Bobby Brown III played 61% at nose tackle, with Tyler Davis playing 11 snaps and Neville Gallimore playing only four snaps.
