OFFICIAL FIGURES ARE THE BOX SCORE AS SCORED. DERIVED FIGURES COME FROM PLAY BY PLAY WITH GARBAGE TIME REMOVED, SO THEY COUNT A DIFFERENT SET OF PLAYS AND WILL NOT TIE OUT AGAINST THE OFFICIAL COLUMN. A BRIGHTENED SIDE LEADS THAT ROW BY THE DIRECTION IN ITS TOOLTIP; TIME OF POSSESSION IS UNMARKED BECAUSE IT IS A TENDENCY, NOT A VIRTUE. SEASON AVERAGES ARE REGULAR SEASON ONLY. MARKET FIGURES ARE BOOK CONSENSUS, NEVER MODEL OUTPUT.
DATA BASISNOTHING ON THIS TAB IS MEASURED YET · 2021 PRESEASON · NO GAMES PLAYED
MEASURED0 OF 12 GAMES
Real 2026 data. It accumulates weekly and replaces carried figures metric by metric, on the schedules below.
CARRIED14 ROOMS
What each roster did last season, applied player by player. Transfers name the school.
PROGRAM PRIOR2 STAFFS
The programme's own prior identity — or, where the staff is new, the coach's career fingerprint with its sample.
PRESEASON FACT6 PER TEAM
Talent, recruiting, vacated usage, portal and coach status. Preseason inputs.
ABSENT2 CLASSES
Current season luck and situational splits. Shown absent with the reason, never estimated.
FLIPS TO MEASUREDABSENTNOT MEASURED. This asks how many weeks into a season each number becomes trustworthy, which is a within-season question. The back-test measures relationships between one season and the next, so it cannot answer it.
