The March 21 NHL card stacks multiple games into a compact early window, which usually increases short-term pregame line movement.
Why this window behaves differently
Saturday slates with many near-back-to-back start times concentrate market attention. When goalie confirmations and final lineup notes arrive close together, books often reprice quickly across several games.
Practical betting takeaway
The edge is less about predicting one headline game and more about timing: compare opening numbers versus final-hour prices and avoid chasing every late move.
