Gold is our distribution, parchment is the Kalshi contract at each strike; the band between them is green where our probability is higher and purple where it is lower. We publish our number only where we have measured it to be calibrated, between 30% and 70%; rungs outside that range show the market only, and a rung where our number sits more than 30 points from a liquid market is refused outright — a gap that size is a bug until proven otherwise. A contract pays $1 if it settles YES, so a price in cents is an implied probability. Prediction markets carry risk; contracts can settle at $0.

How this projection is built
Season projections come from our own usage model — target and carry share, efficiency and games played — then the published rank blends that model with consensus ADP at a weight fitted per position. The raw model loses to consensus ADP at every position, so the board leads with the blend and the disagreement is the content, not a claim that we are right.
The engine behind the game numbers grades at 59.6% straight up across 3,266 games (2013–2024). Those figures grade DAEPA, the underlying play-by-play model. Every published call is graded here.

Questions about Sione Vaki
What are Sione Vaki's Kalshi props for Week 2?
As of Sep 17, 1:00 PM ET, Kalshi lists 4 strikes on Sione Vaki against BUF: 10+ rush yds at 42.5¢, 15+ rush yds at 28.5¢, 20+ rush yds at 18.5¢, 25+ rush yds at 12.0¢. A Kalshi prop contract pays $1 if the threshold is cleared, so the price in cents is the market's implied probability. Every strike on this page carries the sportsbook consensus at the same threshold beside it.
Where is the best price on Sione Vaki 10+ rush yds?
As of Sep 17, 1:00 PM ET, the cheapest over is Kalshi at 44.7¢ (next best 45.9¢). Prices are per $1 of payout — Kalshi net of its fee, sportsbooks at their raw quote — so the two are directly comparable. Cheapest is not the same as correct: compare it to our model's probability for the same threshold before taking a position.
What is Sione Vaki's 2026 projection?
Sione Vaki projects a pending total for 2026. The page also carries a measured 10th–90th percentile range: it is the fitted distribution of actual-over-projected outcomes, holdout-validated, not a simulation.
How does a Kalshi player-prop contract pay out?
A Kalshi player-prop contract settles at $1 if the player clears the stated threshold and $0 if he does not, so the price in cents is the market’s implied probability of the threshold being cleared. Buying YES at 62¢ returns 38¢ per contract on a clear and loses 62¢ otherwise; buying NO at 38¢ is the mirror. Because both sides of a two-sided Kalshi book sum to about 100¢, no de-vigging is needed before comparing it to a model probability — a sportsbook price has to be de-vigged first.
