I like to rely on a couple simple measures of how entertaining a game is, Excitement Index (EI) and Comeback Factor (CBF). From the Glossary:
Excitement Index (EI) – The measure of how exciting a game is. EI measures the total movement of the Win Probability (WP) line during a game. The more that WP fluctuates, the more dramatic, uncertain, and exciting a game is.The 'Best Games' tool on the site is one of the hidden treasures of ANS (in my opinion). For instance, it tells us that the BAL-DEN game ranks as the 5th most exciting game of the entire season. It's also the most exciting game for the both the Broncos and the Ravens in the database (since 2000). And with a CBF of 50, the game ranks behind just 7 games this season with an even more improbable outcome.
Comeback Factor (CBF) – The measure of how big a comeback is in a game. CBF is defined as the inverse of the winning team’s lowest Win Probability (WP) during a game. For example, if a winning team’s lowest point in a game is 0.10 WP, its CBF would be 10, which is 1 / 0.10. The higher the CBF, the bigger the comeback.
But how does the game compare to playoff games? I don't have a filter for playoffs in the tool itself, but here is a list of the highest EI playoff games, including Super Bowls. Week 18 corresponds to the wildcard round, 19 to divisional games, and so on.
