A cover is a settled game where the final margin beat the closing spread; a push is a margin that landed on it. Previous meetings are finished regular-season games between the two teams. The prop rates count the games in which a player's stat reached the line over that player's last 20 games. A posted line is one book's number on one day. Nothing here is a projection.
