Heads up
  • Teammate Amon-Ra St. Brown (a top target) is questionable.

A hurt top target or lead back nudges the projection up a little, since their work tends to shift to teammates. QB and offensive-line flags are shown for context but do not change the number.

How Sione Vaki should do vs the BearsSeason log, the group you pick, and a projection

Season so far, compared with what the group you pick below has done against the Bears, plus a projection for this game.

What is this table?

Rows at the top are every game Sione Vaki has played this season, using the same stat columns as the table above.

Compare against picks which group of Bears 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 Sione Vaki will land in this week, so this is your call, not a guess.

Bears avg is the average line of that group. Difference is that minus Sione Vaki's own average: green means the defense gives that slot more than Sione Vaki usually produces.

Projected is Sione Vaki's recent-weighted average scaled by how generous the Bears 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 Vaki 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 · Sione VakiGood confidence · 3.2 proj pts1/10 start
  • Sione Vaki averages 3.3 PPR points over 7 games (recent-weighted 3.6) and has played as the team's RB2.
  • The Bears have allowed 4.3 points to RB2s over 7 games (-16% vs league). The model applies 70% of that gap because the sample is small, giving a -11% adjustment.
  • Projection: 3.2 points.
  • For reference, a typical weekly starter-level RB scores about 13.1 and a top-tier one about 20.9.

Prediction & chance to scoreSione Vaki vs the Bears

Prediction for Sione Vaki

Nobody knows which slot Sione Vaki will land in this week, so pick the one you expect. The projection changes because each slot faces a different average from the Bears.

If Sione Vaki plays as
3.2
projected PPR points

I predict about 3.2 points for Sione Vaki if playing as a RB2. Sione Vaki has averaged 3.3 over 7 games, and the Bears have given up 4.3 to RB2s (-16% vs the league average of 5.1).

How this projection is built

1. The player. Sione Vaki scored: Wk 1 2.8, Wk 2 3.0, Wk 3 4.7, Wk 4 2.7, Wk 5 1.1, Wk 7 0.5, Wk 8 8.0. Average 3.3; weighted toward recent games it is 3.6.

2. The defense. Over 7 games, the Bears allowed 4.3 points to their opponent's RB2. The league average for that slot is 5.1, so that is -16%.

3. Trusting small samples less. With 7 defensive games, only 70% of the gap is applied, capped at +/-30%. That gives a -11% adjustment (x0.89).

4. Result. 3.6 x 0.89 = 3.2. 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 Sione Vaki is to reach it as a RB2.

43%
chance of 3+ PPR points
Why this percentage?

The projection (3.2) 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 2.5 points, leaning on Sione Vaki'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 3.

With only 7 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
