Kyren Williams
RB
Los Angeles Rams▼ Cold
- Teammate Davante Adams (a top target) is on IR, so Williams may see more targets.
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.
This is how RBs have played against the Bills in the 2026 season.
RB1 = the highest-scoring RB against Bills in each game, not a fixed depth-chart spot.

How Kyren Williams should do vs the BillsSeason log, the group you pick, and a projection
Season so far, compared with what the group you pick below has done against the Bills, plus a projection for this game.
What is this table?
Rows at the top are every game Kyren Williams has played this season, using the same stat columns as the table above.
Compare against picks which group of Bills 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 Kyren Williams will land in this week, so this is your call, not a guess.
Bills avg is the average line of that group. Difference is that minus Kyren Williams's own average: green means the defense gives that slot more than Kyren Williams usually produces.
Projected is Kyren Williams's recent-weighted average scaled by how generous the Bills 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 | +0.3 | -15.8 | +0.0 | -0.5 | -0.4 | -4.8 | +0.6 | +2.3 | |
Difference is what the defense allows minus what Williams averages (green = defense gives up more). Projected stats scale the player's averages by the matchup adjustment, so they are a rough guide.
Prediction & chance to scoreKyren Williams vs the Bills
Prediction for Kyren Williams
Nobody knows which slot Kyren Williams will land in this week, so pick the one you expect. The projection changes because each slot faces a different average from the Bills.
I predict about 25.3 points for Kyren Williams if playing as a RB1. Kyren Williams has averaged 22.4 over 4 games, and the Bills have given up 21.1 to RB1s (+31% vs the league average of 16.0).
How this projection is built
1. The player. Kyren Williams scored: Wk 1 15.5, Wk 2 15.7, Wk 3 21.8, Wk 4 36.7. Average 22.4; weighted toward recent games it is 21.5.
2. The defense. Over 4 games, the Bills allowed 21.1 points to their opponent's RB1. The league average for that slot is 16.0, so that is +31%.
3. Trusting small samples less. With 4 defensive games, only 57% of the gap is applied, capped at +/-30%. That gives a +18% adjustment (x1.18).
4. Result. 21.5 x 1.18 = 25.3. 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 Kyren Williams is to reach it as a RB1.
Why this percentage?
The projection (25.3) 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 11.7 points, leaning on Kyren Williams'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 25.
With only 4 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
- RB1s have averaged 14.3 carries, 52.8 rushing yards and 3.8 receptions against the Bills across 4 games.
- The Bills allow 21.1 PPR points to RB1s, +31% versus the league average of 16.0 (ranked 4 of 32, where 1 is most generous). That is a favorable matchup.
- Outlier: Week 1, David Montgomery (20 car) sits far above the other games and pulls the averages up. Average with it vs without it: car 14.3 vs 12.3. The table above keeps the raw averages.
- 4 of 4 games reached 10+ PPR points. Scores range from 13.7 to 28.9 (median 20.9).
- Every RB1 in the sample cleared 40 rushing yards.
- RB1s scored a touchdown in 4 of 4 games (100%).
