Defensive line. It was another high-snap game for DeForest Buckner, who played 61 of 67 possible defensive snaps, the most of any 49ers defensive lineman. The 49ers coaches are figuring out what last year's staff realized: It's hard to take Buckner out of the game. He doesn't voluntarily come out and he doesn't wear down. He also has one true backup, Xavier Cooper, who for the second straight game was inactive. Through three games, Buckner has played 171 snaps; through three last year he played 164.
One other notable: Defensive end Elvis Dumervil played only 10 snaps. Perhaps that's because at age 33 the 49ers were leery of playing him too much just four days after his last outing. More likely it's because the Rams rarely were in third-and-long situations. Defensive end Aaron Lynch, for instance, played only 14 snaps.

Linebacker. NaVorro Bowman admitted he had a tough time getting up to speed in a short week. Despite 67 snaps and 32 runs by the Rams, Bowman had only four tackles to go along with two mis-tackles. That's four days after having a game-high 10 stops against the Seahawks. Brock Coyle entered the game at linebacker on just two plays, albeit successful goal-line stops. He appeared to suffer a concussion on the third-down play but stayed in the game for fourth down. That also seemed to be the case with fullback Kyle Juszczyk's neck and head injury. It looked like he suffered them on a third-and-goal play but remained in the game for the fourth. Dekoda Watson did not play any snaps on defense despite a foot injury for Eli Harold.

Defensive back. Jimmie Ward, Jaquiski Tartt and K'Waun Williams tied for the team lead in tackles. The game was Ward's first ever at his new single-high safety spot. The Rams had several big plays, but Ward, who played all 67 snaps, did not seem to be the main culprit on them. The team's cornerbacks, however, were continually beaten. Rashard Robinson in particular had a tough outing. According to Pro Football Focus, he allowed three catches on four targets for 66 yards. He also committed three penalties, one of them in the end zone. All of the cornerbacks were beaten at some point by Los Angeles' Sammy Watkins.
Others: CB Dontae Johnson 65, CB Rashard Robinson 65, NCB K’Waun Williams 42, S Jaquiski Tartt 48, Lorenzo Jerome 19.
Running back. Carlos Hyde's first-quarter hip injury allowed Matt Breida (16 snaps) and Raheem Mostert (8) more carries than they normally would have. Breida looked good on his runs -- though he flubbed a short pass attempt -- but Mostert fumbled in the opening quarter. Meanwhile, Hyde did not seem hindered by the injury by the time the second quarter began. He played 61 of 82 possible snaps and fought for extra yardage throughout the game. It was his third straight strong effort. Juszczyk played a season-high 26 snaps despite leaving the game in the third quarter. He was targeted only one in the passing game, but it was a big reception -- for 34 yards. The 49ers were handcuffed when he left. They either used two tight ends or had a tight end, usually George Kittle, line up in the backfield.
Receiver. Pierre Garçon played 69 snaps -- 30 more than Sunday against Seattle -- and Marquise Goodwin played 59. Trent Taylor was on the field for 30 plays as the 49ers were playing catch-up starting midway through the second quarter.
Others: Aldrick Robinson 27, Victor Bolden Jr. 2
Offensive line. Laken Tomlinson drew his second straight tough assignment. The Rams lined defensive tackle Aaron Donald across from him throughout the game and, as you might expect, Tomlinson struggled. According to PFF, he allowed a sack, a hit and two quarterback hurries while also committing a false-start penalty. His 35.3 grade was the lowest of the offensive line. The highest: Joe Staley's. The left tackle usually does well against Robert Quinn and that held true Thursday. He did not allow a quarterback pressure. All five starters played 82 snaps; Garry Gilliam played one.
Tight ends: George Kittle 39, Garrett Celek 36, Logan Paulsen 27
