How Line Watch works
- •Deployment is rebuilt from the official shift charts: the forward trio and defense pair a player shared the most 5-on-5 time with, and the power-play unit he spent most of the man advantage on.
- •Each game is compared with the player's previous five games (at least three), so a change means a change from his own recent role.
- •Changes that last only one game, come out of blowouts or move by a few seconds are filtered out. What remains is ranked by fantasy impact: first-unit power play and top-line moves first.
77 raw deployment changes were checked for this date; 2 passed.
FAQ
What is Line Watch?
Line Watch flags fantasy-relevant role changes from the NHL shift charts: players moving onto or off the first power-play unit, forwards and defensemen moving up or down the lineup, new defense partners, and big swings in ice time. Each night gets its own dated digest.
How is a line change detected?
After every game we rebuild each team's lines, pairs and power-play units from who was on the ice together, then compare every player with his own previous five games. A change only counts once the team has three games of history to compare against.
Why are some line changes left out?
Coaches shuffle lines constantly, so a one-game move is usually noise. Power-play and line moves must hold for at least two straight games (three after a blowout decided by 4+ goals). Ice-time swings must be at least three minutes, not come from a blowout, and either repeat or reach five minutes.
Where do goalie and injury alerts come from?
Goalie flips come from our starting-goalie snapshots, taken every 15 minutes: a different goalie listed, or a confirmed starter going back to expected. Injury notes come from the public injury report, matched to NHL players and limited to regular-lineup players.
