Reading a College Basketball Spread Line
A point spread sets a margin of victory the favored team must exceed for a bet on them to cash. If Duke is -8.5 against UNC, Duke needs to win by 9 or more to cover. The underdog — UNC at +8.5 — covers if they win outright or lose by 8 or fewer. Half-point spreads like .5 eliminate the push entirely,
which is why oddsmakers use them on tight matchups. Lines open early in the week and shift based on wagering volume and injury news, so the number you see Monday morning may look very different by tip-off. Tracking that movement tells you which side the sharper money is hitting.
