The BOS/NYY under is the kind of result that looks obvious in hindsight and is genuinely hard to anticipate beforehand. A 16-run game by one team is a rare event — rare enough that leaning under an 8-run total in a pitching matchup is not an unreasonable position. It was still wrong, and wrong is wrong. The record reflects it.
The DFS side offers a cleaner lesson. Three of our five misses in the worst-calls column were starting pitchers — Bassitt, Suarez, and Imanaga — all of whom allowed six or more earned runs. Pitcher variance on a 14-game Sunday slate is as high as it gets, and the model's confidence intervals around SP projections probably deserve a second look heading into September. When three arms all blow up in the same direction on the same day, that's signal worth examining.
Henderson's 47-point day is the kind of performance that reminds you why DFS construction matters. A $5,800 player who scores 47 is how slates get won. We had him in the system. Whether your lineups captured it is a construction question, not a projection one.
Nothing made the card Sunday. That was the right call. The leans lost us one and pushed the other. We'll be back Monday with the model running and a cleaner look at the board. The ledger is honest, which is the only thing it needs to be.
