Method

Read against .

  • The shuffle keeps the season’s shape: the games are cut in two where one date leaves the least variance, each game is read against its stretch, and the sides are shuffled only inside each stretch.
  • Who played is read from the schools’ box scores’ participation lists for 13 of these 25 games; in the other 12 a player is counted as in them when the box score has a stat for him.
