Glossary
W: Wins, L: Losses, PCT: Winning percentage, RPI: Relative Power Index+, SOS: Strength of schedule , PWR: ESPN Power Ranking , PF: Points scored, PA: Points allowed, ExW-L: Expected W-L*, ExWP: Expected winning percentage*

+The basic formula is 25% team winning percentage, 50% opponents' average winning percentage, and 25% opponents' opponents' average winning percentage.

*ExW-L and ExWP are derived the Pythagorean 16.5 Method, the basketball adaptation of Bill James' Pythagorean theorem of baseball: Runs scored ^16.5 / (Runs scored ^16.5 + runs allowed ^16.5). This formula was designed to relate a team's points scored and points allowed to its won-lost record.
