"Robert Woods was outstanding tonight, being able to come through time and time again with some third downs, some crucial catches," Coach Sean McVay said.
Woods, who signed as a free agent after four seasons with Buffalo, finished the regular season with 56 catches for 781 yards and five touchdowns.
"We're a young team, a very young team," Woods said. "A young quarterback, young receivers. … Hopefully, a lot of these guys put in the work and come back next year."
Rams defensive lineman Michael Brockers was sidelined by a knee injury in the second half.

Morgan Fox, a second-year pro, was inserted at end. In his first series, Fox helped sack Ryan on third down. Fox finished with five tackles, half a sack and two quarterback hits.
Brockers, a cornerstone of defensive coordinator Wade Phillips' 3-4 scheme with 4.5 sacks this season and four deflected passes, finished with half a sack and a quarterback hit. The Rams sacked Ryan three times in the first half but failed to bring him down in the second.
McVay said Brockers was "certainly missed," especially in the run defense.
Atlanta's Devonta Freeman rushed for 66 yards and a touchdown in 18 carries. Tevin Coleman rushed for 40 yards in 14 carries.
"They did a good job of being able to consistently get some runs off," McVay said. "You see Freeman was able to make some hard-earned runs where he's breaking some tackles."
Players for both teams said they had problems with the slick playing field.

He bounced back after missing a field goal and an extra point in his debut at Tennessee.
Linebacker Mark Barron, who sat out most of the previous three games because of injuries, returned to the lineup against the Falcons and had 10 tackles.
Barron, a mainstay of a defense that caused eight turnovers on opponents' first possessions, was held out of the season finale so he'd be ready for the playoffs. But even with Barron back, the Rams failed to force a turnover for the first time in six games, and just the fourth time this season.
