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 | TB | BOS | Why |
|---|---|---|---|
| Team rating | 1567 | 1507 | Elo entering the game; 1500 is league average |
| Home field | — | +35 | Worth 35 Elo in the NHL |
| Starting goalies | +7 | +4 | TB: Andrei Vasilevskiy: team allows 0.17 fewer goals than with its usual starter (≈49 weighted starts) · BOS: Jeremy Swayman: team allows 0.10 fewer goals than with its usual starter (≈48 weighted starts) |
| Elo ratings | TB +28 Elo | TB 54.0% | |
| Market-implied ratings | TB 52.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TB 53.1% | 20% Elo, 80% market-implied (log-odds blend) | |
| Forecast | TB 51.1% | 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.
