Track the slate as officials arrive, then scan league-specific trends without leaving the assignment board.
NBA, WNBA, and NFL assignments are usually posted earlier, making them stronger morning-check sports.
NCAA and MLB often post closer to tipoff or first pitch, so teams and times show first while signals populate as crews arrive.
Values show the trend first. The smaller line below translates that number into a simple label like Strong Over, Home Edge, or Neutral.
