How Kirk Cousins should do vs the 49ersSeason log, the group you pick, and a projection
Season so far, compared with what the group you pick below has done against the 49ers, plus a projection for this game.
What is this table?
Rows at the top are every game Kirk Cousins has played this season, using the same stat columns as the table above.
Compare against picks which group of 49ers opponents to line them up with: the best QB they faced in each game (1), the second best (2), the third best (3), or all of the top three. Nobody knows which slot Kirk Cousins will land in this week, so this is your call, not a guess.
49ers avg is the average line of that group. Difference is that minus Kirk Cousins's own average: green means the defense gives that slot more than Kirk Cousins usually produces.
Projected is Kirk Cousins's recent-weighted average scaled by how generous the 49ers were to the slot you picked. Change the slot and the projected points change, because each slot has a different matchup adjustment. Picking Top 3 uses the usual-role projection.

Difference is what the defense allows minus what Cousins averages (green = defense gives up more). Projected stats scale the player's averages by the matchup adjustment, so they are a rough guide.
Start / Sit · Kirk CousinsGood confidence · 18.3 proj pts5/10 start
- Kirk Cousins averages 20.0 PPR points over 8 games (recent-weighted 21.2) and has played as the team's QB1.
- The 49ers have allowed 15.1 points to QB1s over 7 games (-8% vs league). The model applies 70% of that gap because the sample is small, giving a -6% adjustment.
- Last season's average (10.4) is blended in at 20% weight because this season's sample is small.
- Game environment +1%: Vegas total 51.5, implied 20.8 points for LV (league avg 22.6); Underdog by 10: likely to pass more while trailing; Mild weather (71F, 7 mph wind): no weather adjustment.
- Opposing-defense injuries (+1%): Opposing starter Upton Stout (CB) is questionable, which helps the passing game.
- Projection: 18.3 points.
- For reference, a typical weekly starter-level QB scores about 19.1 and a top-tier one about 23.8.
- A statistical model from box scores, Vegas lines, weather and injury tags. It cannot see role changes or in-game events.
Prediction & chance to scoreKirk Cousins vs the 49ers
Prediction for Kirk Cousins
Nobody knows which slot Kirk Cousins will land in this week, so pick the one you expect. The projection changes because each slot faces a different average from the 49ers.
I predict about 17.9 points for Kirk Cousins if playing as a QB1. Kirk Cousins has averaged 20.0 over 8 games, and the 49ers have given up 15.1 to QB1s (-8% vs the league average of 16.5).
How this projection is built
1. The player. Kirk Cousins scored: Wk 1 13.8, Wk 2 20.2, Wk 3 22.2, Wk 4 22.6, Wk 5 13.7, Wk 6 18.5, Wk 7 20.4, Wk 8 28.2. Average 20.0; weighted toward recent games it is 19.0.
2. The defense. Over 7 games, the 49ers allowed 15.1 points to their opponent's QB1. The league average for that slot is 16.5, so that is -8%.
3. Trusting small samples less. With 7 defensive games, only 70% of the gap is applied, capped at +/-30%. That gives a -6% adjustment (x0.94).
4. Result. 19.0 x 0.94 = 17.9. Switching slots only changes step 2 and 3: the player's own numbers stay the same, but each slot faces a different defensive average.
It is a statistical model, not knowledge of injuries, game script or weather.
Chance to score
Type a point total to see how likely Kirk Cousins is to reach it as a QB1.
Why this percentage?
The projection (17.9) is the middle of the range. Fantasy scores swing a lot from game to game, so the model spreads possible scores around it by about 7.2 points, leaning on Kirk Cousins's own game-to-game swings once there are several games (and on typical QB swings before that).
Scores are modelled as right-skewed, since a big game is possible but a very negative one is not. The percentage is the share of that spread at or above 18.
With only 8 games of history, treat this as a rough gauge. It gets sharper as the season goes on. It is never lower than 1% or higher than 99%.
InsightsPlain-English takeaways from the table
- QB1s have averaged 222.0 passing yards, 1.4 passing TDs and 4.7 rushing yards against the 49ers across 7 games.
- The 49ers allow 15.1 PPR points to QB1s, -8% versus the league average of 16.5 (ranked 22 of 32, where 1 is most generous). That is a near-average matchup.

- Outlier: Week 1, Matthew Stafford (4.1 pts) sits far below the other games and drags the averages down. Average with it vs without it: pts 15.1 vs 16.9. The table above keeps the raw averages.
