Playoff Simulations

The following predictions come from a game prediction model I trained on historical college football games. The inputs into the game prediction model are team level measures of offensive/defensive/special teams efficiency, which I estimate from play by play data. I simulate each game thousands of times in order to estimate the home team’s win probability and expected margin of victory (or defeat).

About the Table

Team Ratings refer to the team’s estimated efficiency on offense and defense in terms of expected points added per play, adjusted for opponent quality.

Win Probabilities refer to the proportion of simulations in which the team won their matchup in each round.

Game Predictions

About the Table

Quality indicates the quality of the teams involved in the game. This is the (harmonic) mean of the two team’s power ratings and is scaled to range from 0 to 100, with 100 indicating a game between highly rated opponents.

Interest indicates how interesting a game is expected to be based on the quality of the teams and how competitive the game is expected to be. I assign every game a competitive rating using a quadratic formula applied to Pr(HomeWin), which I use along with Quality in a weighted average to produce the Interest score. This ranges from 0 to 100, where 100 indicates a very competitive game between two highly rated opponents.

Pr(HomeWin) is the percentage of times that the home team won the game across every simulation.

Prediction is the average margin of victory for the winning team across all simulations.
