The Basketball Power Index (BPI) is a predictive rating system for college basketball teams, designed to measure team strength and project performance. It is a power rating that can be used to determine how much better one team is than another. A high BPI is good as it indicates that a team is strong relative to the average team. It is calculated by factoring in elements within the game, such as the number of possessions, the margin of victory, and the pace of the game. It also takes into account external factors like the number of days of rest, travel distance, and altitude. ESPN's BPI has proven to be a useful tool for predicting tournament brackets, with a 66% correct pick rate.

What You'll Learn
BPI is a predictive rating system for college basketball
The College Basketball Power Index, or BPI, is a predictive rating system designed by ESPN for college basketball. It was created in 2011 after ESPN analysts requested an alternative to the RPI system. BPI is a measure of team strength and is meant to be the best predictor of performance going forward. It represents how many points above or below average a team is and can be used to determine how much better one team is than another.
BPI is calculated by simulating each team's schedule 10,000 times to produce season-level outcomes. It accounts for several variables, including opponent strength, pace of play, site, travel distance, days of rest, and altitude. By adding in pace and efficiency components, BPI can also project a team's margin of victory.
BPI has proven to be a valuable tool for bracket-making before the start of a tournament. For example, since the 2007 NCAA Basketball Tournament, using BPI to fill out a bracket would have yielded a 66% correct pick rate, compared to 61% for RPI.
While BPI has performed well, it is not perfect and can be improved. It is important to note that BPI is not a predictor of which teams will be in the NCAA Tournament, nor does it determine which teams deserve to be in the tournament. Instead, it helps identify the best and most deserving teams in the country.

BPI measures team strength and projects performance
The College Basketball Power Index (BPI) is a predictive rating system designed to measure team strength and project performance. It was created by ESPN in 2011 to rate college basketball teams and identify the ones most deserving to make the NCAA Tournament.
BPI is a power rating that can be used to determine how much better one team is than another. It is a more accurate predictor of a team's performance than other rating systems like RPI, which is the primary rating system used by the NCAA Tournament Selection Committee. BPI factors in elements within the game, not just the final result. It takes into account the margin of win/loss, the number of possessions a team has, and the pace of the game.
BPI also considers factors such as the number of days' rest for each team, the difference in distance traveled from home, and high-altitude effects. It produces a team's percentage chance of winning any game and can project a team's margin of victory. Each team's schedule is simulated 10,000 times to produce season-level outcomes such as each team's chance to win a share of its conference title or its projected strength of schedule.
BPI has proven to be a valuable tool for bracket-making before the start of a tournament. Since the 2007 NCAA Basketball Tournament, using BPI to fill out a bracket would have yielded a 66% correct pick rate, compared to 61% for RPI. However, it is important to note that BPI is not a perfect predictor of team performance and there will be teams and projections that don't always make sense.

BPI is a better tool for filling out brackets
The College Basketball Power Index (BPI) is a useful tool for filling out brackets. It is a measure of team strength that predicts performance. BPI represents how many points above or below average a team is. It is calculated using eight categories of stats, including points scored, rebounds, assists, and blocks. It also takes into account the number of days of rest for each team, the distance travelled, and the altitude effects.
Another advantage of BPI is that it factors in elements within the game, not just the final result. It takes into account the margin of win/loss, but doesn't equate a 40-point win as twice as impressive as a 20-point win. BPI also examines the number of possessions a team has to determine the pace of the game. This is important because the pace dictates the number of scoring opportunities, which affects the scoring margin.
Additionally, BPI does not assume that every win against the same team is equal. It takes into account the strength of the opponent and the difficulty of the game. This is important because it provides a more accurate assessment of a team's performance and predicts future performance more effectively.
BPI also offers a nuanced way of looking at team matchups. Instead of just picking the higher-ranked team to win each matchup, BPI determines the percentage chance of each team advancing to each round. This helps to identify potential upset picks and undervalued or overvalued teams. For example, in 2014, Florida's chances of advancing to the Sweet 16 and beyond were overestimated by the public, but BPI took into account the strength of their opponents and determined that their advancement was less likely than fans predicted.

In summary, BPI is a comprehensive rating system that considers various factors within the game to predict team performance and facilitate comparisons between teams.

BPI is a solid predictor of college basketball games
The College Basketball Power Index, or BPI, is a predictive rating system for college basketball. It was created by ESPN in 2011 to provide a better tool for evaluating and ranking college basketball teams. The BPI is designed to measure team strength and project performance by accounting for various factors such as opponent strength, pace of play, site, travel distance, days of rest, and altitude.
Another advantage of BPI over other rating systems is its ability to account for unique game factors. For example, most home-court advantages are captured in the game site variable, but BPI also recognizes that a cross-country trip to an opponent's home court can impact a team's performance. Similarly, BPI considers the number of days of rest for each team and high-altitude effects, which can be predictive in extreme cases.
BPI has proven to be a valuable tool for bracket-making and predicting tournament outcomes. Since the 2007 NCAA Basketball Tournament, using BPI to fill out a bracket would have resulted in a 66% correct pick rate, compared to 61% for RPI. While BPI has not been adopted by the NCAA Tournament Selection Committee, it has gained traction among fans and analysts as a more comprehensive and accurate ranking system for college basketball teams.
