How Justin Jefferson 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 Justin Jefferson 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 WR they faced in each game (1), the second best (2), the third best (3), or all of the top three. Nobody knows which slot Justin Jefferson 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 Justin Jefferson's own average: green means the defense gives that slot more than Justin Jefferson usually produces.

Projected is Justin Jefferson'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.

Start / Sit · Justin JeffersonMedium confidence · 14.0 proj ptsStart

Justin Jefferson usually plays as the team's WR1, so the verdict uses the WR1 numbers, not the slot selected above.

  • Justin Jefferson averages 19.9 PPR points over 2 games (recent-weighted 18.6) and has played as the team's WR1.
  • The 49ers have allowed 13.6 points to WR1s over 2 games (-20% vs league). The model applies 40% of that gap because the sample is small, giving a -8% adjustment.
  • Last season's average (11.9) is blended in at 50% weight because this season's sample is small.
  • Projection: 14.0 points.
  • For reference, a typical weekly starter-level WR scores about 11.8 and a top-tier one about 20.8.
  • A statistical model from box scores, Vegas lines, weather and injury tags. It cannot see role changes or in-game events.
Prediction & chance to scoreJustin Jefferson vs the 49ers

Prediction for Justin Jefferson

Nobody knows which slot Justin Jefferson will land in this week, so pick the one you expect. The projection changes because each slot faces a different average from the 49ers.

If Justin Jefferson plays as
14.0
projected PPR points

I predict about 14.0 points for Justin Jefferson if playing as a WR1. Justin Jefferson has averaged 19.9 over 2 games, and the 49ers have given up 13.6 to WR1s (-20% vs the league average of 17.0).

How this projection is built

1. The player. Justin Jefferson scored: Wk 1 31.2, Wk 2 8.5. Average 19.9; weighted toward recent games it is 15.2.

2. The defense. Over 2 games, the 49ers allowed 13.6 points to their opponent's WR1. The league average for that slot is 17.0, so that is -20%.

3. Trusting small samples less. With 2 defensive games, only 40% of the gap is applied, capped at +/-30%. That gives a -8% adjustment (x0.92).

4. Result. 15.2 x 0.92 = 14.0. 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 Justin Jefferson is to reach it as a WR1.

42%
chance of 14+ PPR points
Why this percentage?

The projection (14.0) 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 8.4 points, leaning on Justin Jefferson's own game-to-game swings once there are several games (and on typical WR 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 14.

With only 2 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%.
