It was clear Dre Greenlaw’s return gave the 49ers' defense a burst of energy in their 12-6 loss to the Los Angeles Rams on Thursday at Levi's Stadium, but the offense couldn’t do enough to manage a win.
San Francisco's PFF grades show a lopsided affair between the two sides of the ball. Fred Warner played even better with his partner back beside him, receiving the defense's top grade. Kyle Shanahan was impressed with Greenlaw’s return.
“Dre, he's an amazing player and it's not the first time he did that,” Shanahan said.” A few years ago, his first game that he got hurt in Week 1 versus Detroit, and the next time he played was in Week 17 versus the Rams when we needed to win that to go to the playoffs.

“And that game, I thought he had one of the best games I've ever seen a linebacker play, and it was looking a lot like that last night, too. Exactly the same, it was just only a half a football, but it was amazing."
The offense struggled under heavy rainfall in the first half of the game and made mistakes throughout the contest. Brock Purdy and his teammates were unable to find their way into the end zone after putting up 38 points just five days prior in a blowout win over the Chicago Bears.
Here are the 49ers' PFF grades from Week 15:

WR Deebo Samuel - 44.7
The wide receiver only caught three of his seven targets for 16 yards and carried the ball twice for 3 yards.
QB Brock Purdy - 54.7
Three of Purdy’s four lowest passing totals as a starter in the regular season have come in his last four starts, with the quarterback completing only 14 of his 31 attempts for 142 yards and no touchdowns with an interception.
The signal-caller attempted to stretch the field with an average depth of target of 11.9 yards (second-highest of 2024), but Purdy only was able to connect on one deep attempt for 33 yards, and his lone interception.
Purdy came into the game completing 53.6 percent of his deep throws 20 or more yards downfield, which led the NFL.
After using play action on a season-high 41 percent of his drop backs last week, Purdy used play action only three times Thursday (8.8 percent) and went 0-for-3 passing.
OL Dominick Puni - 57.3
After allowing just one sack all season, Puni gave up two Thursday, including one on the last play of the game that eliminated the chance of a Hail Mary attempt.

The group as a whole allowed a whopping 18 pressures, while tight end Eric Saubert allowed one.
