Prediction for RJ Harvey
Nobody knows which slot RJ Harvey 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 10.3 points for RJ Harvey if playing as a RB1. RJ Harvey has averaged 8.1 over 1 game, and the 49ers have given up 13.9 to RB1s (-11% vs the league average of 15.7).
How this projection is built
1. The player. RJ Harvey scored: Wk 1 8.1. Average 8.1; weighted toward recent games it is 10.8.
2. The defense. Over 2 games, the 49ers allowed 13.9 points to their opponent's RB1. The league average for that slot is 15.7, so that is -11%.
3. Trusting small samples less. With 2 defensive games, only 40% of the gap is applied, capped at +/-30%. That gives a -4% adjustment (x0.96).
4. Result. 10.8 x 0.96 = 10.3. 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 RJ Harvey is to reach it as a RB1.
Why this percentage?
The projection (10.3) 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 6.2 points, leaning on RJ Harvey's own game-to-game swings once there are several games (and on typical RB 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 10.
With only 1 game 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%.

- RJ Harvey averages 8.1 PPR points over 1 game (recent-weighted 8.1) and has played as the team's RB1.
- The 49ers have allowed 13.9 points to RB1s over 2 games (-11% vs league). The model applies 40% of that gap because the sample is small, giving a -4% adjustment.
- Last season's average (12.2) is blended in at 67% weight because this season's sample is small.
- Injury report: Out. The projection assumes the player plays.
- Projection: 10.3 points.
- For reference, a typical weekly starter-level RB scores about 12.2 and a top-tier one about 20.0.

RJ Harvey's stats vs the 49ers
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 RJ Harvey 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 RB they faced in each game (1), the second best (2), the third best (3), or all of the top three. Nobody knows which slot RJ Harvey 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 RJ Harvey's own average: green means the defense gives that slot more than RJ Harvey usually produces.
Projected is RJ Harvey'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.
| Wk | Opp | Car | RuYd | RuTD | Tgt | Rec | ReYd | ReTD | FPts |

| Harvey avg | 3.0 | 18.0 | 0.0 | 4.0 | 4.0 | 23.0 | 0.0 | 8.1 | |
| 49ers RB1 avg | 15.5 | 57.5 | 0.5 | 4.5 | 3.0 | 21.5 | 0.0 | 13.9 | |
| Difference | +12.5 | +39.5 | +0.5 | +0.5 | -1.0 | -1.5 | +0.0 | +5.8 | |
| Projected as RB1 | 2.9 | 17.2 | 0.0 | 3.8 | 3.8 | 22.0 | 0.0 | 10.3 | |
Difference is what the defense allows minus what Harvey averages (green = defense gives up more). Projected stats scale the player's averages by the matchup adjustment, so they are a rough guide.
