Spread analysis
The Rams have won five games in a row and have gone 4-1 ATS over that span. With a win, they would claim the second seed in the NFC but a defeat, along with an Arizona victory, would cause them to lose the divisional title and be forced to play on the road in the wild card round.
The 49ers have also played very well lately, going 6-2 SU and ATS in their last eight games, including a 31-10 beatdown of the Rams in Week 10. In what seems like an annual occurrence, the 49ers have been absolutely wrecked by injuries but two areas, in particular, stand out for Sunday: quarterback and the secondary.
Starting QB Jimmy Garoppolo is listed as questionable with a torn ligament in his right (throwing hand) thumb. While he practiced on Wednesday, he admitted to reporters that "it f*****g hurts" in a display of honesty we hadn't seen in an NFL interview since... earlier that day when Aaron Rodgers called Hub Arkush a bum. If he does play, it's tough to see that injury not affecting his arm strength and accuracy and if he doesn't, rookie Trey Lance will make his third start.
San Francisco traded up to take Lance with the third pick in the draft and while he looked good in the second half of last week's victory against the Texans, it is the Texans we're talking about here. Lance did not look sharp in his previous start, against the Cardinals in October, and things won't be as easy with Aaron Donald and Von Miller chasing him.
As for the 49ers' secondary, it could be missing as many as five key players due to COVID-19. That will be tough to deal with even if they get back cornerback Emmanuel Moseley, who has missed the last month with an ankle injury.
The Rams love to air it out and wide receiver Cooper Kupp is within striking distance of the NFL record for catches and receiving yards in a season. While Rams QB Matthew Stafford has turned the ball over way too much lately, he has still thrown for the second-most yards and touchdowns in the NFL and will be facing a San Fran defense that has the second-fewest interceptions in the league.
The 49ers have owned this rivalry in recent meetings but expect the Rams to win and cover on Sunday.
Prediction: Rams -4.5 (-110)
Over/Under analysis
The Niners have played very well on defense over the last two months and since Week 10, they are ninth in NFL in EPA/play allowed while ranking fifth in success rate.
The Rams also have a very strong defense, led by Donald and shutdown cornerback Jalen Ramsey. Los Angeles ranks fifth in the league in DVOA defense and in its last five games has allowed just 16.4 points per game.
The Under has cashed in four straight games for San Francisco and has also hit in three straight meetings between these divisional foes. With the Rams going a sizzling 16-5 to the Under in their last 21 games at home, expect another lower-scoring battle between a pair of rivals that both have something to play for.
Prediction: Under 44.5 (-110)
Best bet
If Aaron Donald didn't know who 49ers wide receiver Deebo Samuel was last year, he definitely does this season after Samuel broke out with 1,310 receiving yards and 320 rushing yards in 15 games.
Those receiving numbers are all the more impressive when you consider that Samuel logged just three catches from Weeks 11 through 14. There was a good reason for what seemed like a slump. Samuel rushed for 79 yards and a score against the Jags in Week 11 before the Niners abandoned the passing game after taking a huge early lead. In Week 12 he left the game against the Vikings due to a groin injury, missed the following week, and came back in Week 14 but was nowhere near 100 percent.
However, he has looked like his usual explosive self in the last three weeks, picking up 63 and 60 yards in blowout wins against Atlanta and Houston while racking up 159 receiving yards in a close loss to the Titans.
The Rams have a fantastic corner in Ramsey but 49ers coach Kyle Shanahan does a great job of moving Samuel around to prevent defenses from keying on him. That worked to great effect earlier this season when Samuel had five catches for 97 yards and a pair of scores versus L.A. With Deebo's receiving yards number set a relatively low number, hit the Over.
Pick: Deebo Samuel Over 54.5 receiving yards (-110)
