How to read the prices

Over means more than the posted line; Under means fewer. Decimal odds show the total return per unit staked, including the stake. Row order follows lineup status and available prices, not a confidence ranking.

Getting a better price than most bookmakers offer is the only thing that made money in our past tests, measured on WNBA bets; NBA has not been measured yet. Player rates are context, not tips.

Lineups

Expected starting lineup, not yet confirmed

Playing time

No playing-time estimates are available.

Rest

Both teams had at least two days between their last game and this one.

Bookmakers

Full player-line feed has no entries in this view. This does not confirm that bookmakers have posted no lines.

When a player is out, that player's lines are removed: in our past results this helped. Guessing which teammates benefit was also tested and lost money, so nothing else on this page is adjusted for it.

Defense by position

How much this is worth

Defense-by-position numbers are mostly random from season to season; shown for context only. We tested it: a team's defense-by-position numbers from one half of the season do not predict the other half, so treat them as noise.

BOS gives up 104.3 points a game · 3rd of 30 · league average 113.4−9.1 vs average

MIA gives up 121.1 points a game · 26th of 30 · league average 113.4+7.7 vs average
