NFL SECOND-HALF LINES

Second-half lines are new markets posted around halftime. They reflect the score, possessions, injuries, performance, and expectations for the remaining half rather than simply dividing the pregame line by two.

What this guide answers
This guide explains the sortable second-half line context on Only the Overs without presenting live markets as guaranteed opportunities.
- Halftime lines are distinct from full-game lines
- Record the exact timestamp
- Account for score and possession context
- Do not grade a second-half forecast against the full-game result
What changes at halftime
The market has observed real plays, efficiency, injuries, pace, and game state. It also knows which team will receive the second-half kickoff. All of that can make the new spread and total differ from a simple pregame adjustment.
Data can be brief and volatile
Second-half markets may appear for a limited window and move quickly. The site polls public live sources on bounded schedules, preserves the last observation, and labels unavailable data rather than fabricating a line.
Evaluate the remaining period
A second-half total covers points after halftime under the market's settlement rules. Compare a model of remaining possessions and scoring with that same period, then confirm the displayed source and line.
Frequently asked questions
Is a second-half line half of the pregame line?
No. It is a separate market informed by the first half and current game state.
Why might a second-half line disappear?
The market window may close or the public source may stop displaying it. Missing data should remain missing.
