Ranked from each game's win probability as it was played (ESPN's for football and basketball; ours, from the goals, for hockey): how in doubt it was near the end, how far the winner came back from, how late it was decided, how big its momentum swings were and how often a team erased a deficit, with a bonus for overtime. That drama is then weighted by how good a matchup it was going in (its pre-game Watchability score), so a thriller between top teams ranks above an equally wild game between minor ones.
