NHL is the most goalie-dependent major sport. One position can swing the game probability by 5-10 percentage points, more than any other sport's positional dependency. That makes goalie news the dominant input — and sportsbook reactions to goalie news the dominant edge opportunity.
Goalies are everything
When the starting goalie changes 90 minutes before puck drop because of illness or injury, the moneyline can move 30-50 cents instantly at sharp sportsbooks — and lag at slower US sportsbooks for 15-30 minutes. That window is the sharpest single edge in NHL betting.
