Los Angeles handed the keys to an offense that can be one of the most explosive in football to Matthew Stafford, parting ways with Jared Goff and some significant draft capital to acquire him from the Detroit Lions.
Stafford joins a team that was two wins away from the Super Bowl last season, the Rams undone by league MVP Aaron Rodgers and the Green Bay Packers in the Divisional Round of the playoffs.
The Rams are gambling that Stafford's arrival gets them back to the sport's grandest stage.
However, the financial pressures facing Los Angeles mean the Rams' roster is likely to look very different in 2021.
What will their remodelled group need to do to realise their ambitions next season?
Here we try to answer that question by looking back at the Rams' 2020 campaign using Stats Perform data.
Offense
It is not difficult to see why Sean McVay lost patience with Goff, the number one overall pick of the Rams in the 2016 draft.
The Rams finished the season 18th in yards per play with 5.54, their second successive year outside the top 10 in that regard having been second in 2018 (6.36) when they reached the Super Bowl.
Goff's inability to hang on to the football played a contributing role in their struggles to move the ball more efficiently.
His 17 giveaways were tied for the fourth-most in the NFL while 73 of his 182 incompletions were down to poor throws. Only nine quarterbacks delivered more poor throws in 2020.
Just 14 of Goff's incompletions were drops, tied for 20th among quarterbacks with at least 50 attempts, indicating his receivers were relatively reliable.
Goff had decent success going downfield. His passer rating of 103.4 on throws of 21 or more air yards ranked 10th among quarterbacks to have attempted 25 such throws.
Stafford, however, ranked fifth with a rating of 118.5 and attempted 57 such passes to Goff's 36 at a better completion percentage (35.1 to 33.3), illustrating his greater willingness to push the ball deep and his superior prowess as a downfield thrower.
The Rams will want to give Stafford more support than Goff received from the running game, which averaged 4.27 yards per attempt last year, putting them 17th in the NFL.
Cam Akers' progress could be key in that regard. The 2020 second-round pick came on strong down the stretch and proved himself a big-play threat.
He had four rushes of at least 20 yards with his average distance of 41.8 yards on those carries the most among rookie running backs to have more than one such attempt.
But any progress the offense makes may be cancelled out if the defense takes a step back from its position among the league's elite.
Defense
By many measures, the Rams had the best defense in football last season.
Los Angeles ranked first in opponent yards per play allowed (4.56) in 2020, with their dominance encompassing both the passing game and the run game.
Indeed, the Rams allowed the least passing yards per play (5.08) and the third-least rushing yards per play (3.76).
Just 46.8 per cent of offensive plays run against them were successful, with only three defenses performing better by that measure. The Rams were the third-best team in the league at stopping teams on the critical third and fourth downs, allowing a success rate of 35.9 per cent.
Their numbers in terms of takeaways were not quite as impressive, the Rams finishing with 22, seven shy of the league-high 29 set by the Miami Dolphins.
Though the Rams perhaps did not take the ball away as much as they would have liked, Los Angeles still excelled at preventing opponents from scoring.
Los Angeles finished the year first in opponent scoring efficiency, allowing scores on 51 of 183 opponent drives.
The Rams' defense was led by another Defensive Player of Year effort from star defensive lineman Aaron Donald.
Donald's sack total of 13.5 was a low number by his lofty standards, but he was the clear leader in knockdowns and hurries, his combined total of 94.5 comfortably outstripping the man he beat to the DPOY award, T.J. Watt (83).
There is little to suggest Donald will not continue to dominate but, for the Rams to remain the league's best on defense, they will need to adapt to the loss of coordinator Brandon Staley - who was replaced by Raheem Morris - and the likely departures of several key pieces.
Offseason
The Rams' move to land Stafford came at a high price, leaving them with a distinct lack of capital with which to furnish the roster around him.
Los Angeles traded a third-round pick this year along with first-rounders in 2022 and 2023 to acquire Stafford, leaving them without a first-round selection until 2024.
With Donald and Jalen Ramsey in place for the long term, the defense looks in pretty good hands, but it may be a little top-heavy given the talent the Rams look likely to lose on that side of the ball.
Safety John Jonson, cornerbacks Darious Williams and Troy Hill, and edge rusher Leonard Floyd are all set to hit the market in a year where the Rams are projected to be nearly $30million over an assumed salary cap of $185m.
Replenishing those positions, and sourcing a replacement for unrestricted free agent guard Austin Blythe, will be priorities for the Rams, along with finding a deep threat who can help them harness the most of Stafford's upside throwing the deep ball.
The problem is that the Rams, as it stands, only have three picks in the 2021 NFL Draft with which to add to their group.
That number will go up when compensatory selections are factored into the equation, but the reality is that the Rams will not be as deep as in previous years.
Los Angeles will need to get creative to bolster the roster this offseason, yet the fate of the Rams' 2021 campaign rests predominantly on the success of their bet on Stafford to be a significant upgrade on the quarterback they were so eager to ship out.
