RPI Rankings

CSBN publishes the only quantatative RPI rankings each summer season. We compile a database of some 8,000 players on the rosters of teams in 30+ summer leagues. We score each player based on the competition level of his college program. Using these roster scores we calibrate leagues strength of schedule, which is used to weight game results.




Each summer CSBN college interns report on summer ball play from coast-to-coast. These talented future sportcasters write articles and host video interviews with league officials, players and coaches.
