How the number is built
Elo inputs in rating points (higher favors that team; 25–28 Elo is about a point of spread in football and basketball), then how the pieces combine.
| Factor | BOS | NYI | Why |
|---|---|---|---|
| Team rating | 1477 | 1470 | Elo entering the game; 1500 is league average |
| Home field | — | +35 | Worth 35 Elo in the NHL |
| Starting goalies | 0 | −4 | BOS: Jeremy Swayman: team allows 0.00 more goals than with its usual starter (≈46 weighted starts) · NYI: Ilya Sorokin: team allows 0.09 more goals than with its usual starter (≈46 weighted starts) |
| Elo ratings | NYI +25 Elo | NYI 53.6% | |
| Market-implied ratings | NYI 59.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | NYI 58.0% | 20% Elo, 80% market-implied (log-odds blend) | |
| Forecast | NYI 59.9% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
Tale of the tape
This season coming into the game, regular season, each number with its league rank (the longer the bar, the higher). Home and road: the host's record at home against the visitor's on the road. Overtime and shootout losses count as losses in these records. Opponent Elo: how strong the teams each has played are, 1st the toughest. Shot share is a team's share of the shots on goal in its games. PDO adds shooting and save percentages: far from 100 tends to even out.
