EFFICIENCY GAP

The imported matchup analysis identifies a separation in offensive or defensive efficiency. The flag's accompanying description gives the applicable metric and observed gap.

Definitions describe how Matchup Lab computes and labels saved data. They are descriptive, not predictions, and not betting advice.

ATS COLDAn archived CFB against-the-spread record covered at most 20% of five or more decided lines. This historical label is informational, not advice.
ATS HOTAn archived CFB against-the-spread record covered at least 80% of five or more decided lines. This historical label is informational, not advice.
BACKUP QBThe imported availability report identifies the season starting quarterback as unavailable or replaced by a backup. Check the listed player and source date; this is not a numerical player-value adjustment.
BIG UPSET LAST WEEKA CFB team won its last game as an underdog of at least seven points.
