Mavericks vs Celtics Best Pick, Prediction and Odds

Bet the Celtics on the moneyline. Our rating gives Boston at home 91.1%; the price gives them 84.8%.

The Dallas Mavericks are +530 and the Boston Celtics -750 at DraftKings. With the margin out, that is 15.2% for Dallas and 84.8% for Boston. Our number puts Boston 6.3 points higher than that. We bet at 5.

How 91.1% is reached

Our number comes from a team rating. Every game since the start of 2025-26 moves a team’s rating up after a win and down after a loss. A wide margin moves it more, and so does a result against a strong opponent. The rating moves fast enough that a team playing better or worse than before shows within a few games. The home team gets a fixed edge of 100 rating points.

The Celtics are rated 1745.0, second of 30. The Mavericks are rated 1440.5, 20th of 30. The league average is 1500. The ratings were built on 15 November 2026 at 03:38 UTC and include 12 Celtics games and 13 Mavericks games from this season. With Boston’s home edge added, the rating gives the Celtics 91.1% and the Mavericks 8.9%.

The margin is the extra a book builds into both prices so the pair comes to more than 100%. At -750 and +530 they come to 104.1%. Taken out, the Celtics are 84.8% and the Mavericks 15.2%.

For context only, last season’s records produce a different figure. Averaging Boston’s home win rate with Dallas’s road loss rate gives the Celtics 74.1%, which is below the market. That figure is no longer the number the call uses. The rating replaced it because it reads this season as it happens.

This season so far

The Celtics are 10-2, 5-0 at TD Garden and 10-1 against the Eastern Conference. Their last game was a 98-93 win at the Toronto Raptors on Wednesday 11 November. All 12 of those games are in the rating.

The Mavericks are 7-6, 2-4 on the road and 3-5 against the Western Conference. They lost 127-117 at the Cleveland Cavaliers on Saturday 14 November, the night before this game. All 13 are in the rating. Neither the travel nor the injury list is.

Boston at home, Dallas on the road

These are last season’s splits. They describe the matchup and are not the source of our number. In 2025-26 the Celtics went 30-11 at home, scoring 114.8 points a game and allowing 107.0, a margin of 7.8. The Mavericks went 10-30 on the road, scoring 112.0 and allowing 119.3, a margin of -7.3. Dallas’s 40 road games leave out one game at a neutral site. Boston played none.

The other halves: Boston on the road went 26-15, scoring 114.9 and allowing 107.3. Dallas at home went 16-25, scoring 116.3 and allowing 119.9. Boston’s margin barely changed between the two venues, 7.8 at home and 7.6 away. Dallas’s margin was worse by road, -3.6 at home and -7.3 away.

The season around it

The Celtics finished 2025-26 at 56-26, the 2 seed in the East. They scored 114.9 a game, allowed 107.2 and won by 7.7 points a game. They won 38 games by 10 or more and lost 10 by that much. In games decided by 5 points or fewer they went 10-10. They played one overtime game. Their playoffs ended in a 4-3 series loss to the Philadelphia 76ers.

The Mavericks finished 26-56, 12th in the West, and missed the playoffs. They scored 114.1 a game, allowed 119.6 and lost by 5.5 a game. Nine wins came by 10 or more, and 30 losses did. In close games they went 8-10, with six overtime games.

Boston won both meetings by double figures. The Celtics won 110-100 in Dallas on Tuesday 3 February 2026 and 120-100 in Boston on Friday 6 March 2026. Both games fall inside the rating, which counts every game since the start of 2025-26.

Pick: Celtics -750

Bet the Celtics on the moneyline at -750. The gap is 6.3 points toward Boston, against a threshold of 5.

The line read Celtics -750 and Mavericks +530 on 15 November 2026 at 04:32 UTC, DraftKings via ESPN. It opened at Celtics -610 and Mavericks +450. With the margin out, the open gave Boston 82.5%, so the market has moved 2.2 points toward the Celtics since.

What kills the bet

A price on Boston shorter than the rule allows. At -622 or longer the Celtics are a bet whatever Dallas is priced at. With the Mavericks held at +530, Boston stays a bet at any price up to -2000.

The Mavericks cannot become the bet at this kind of price. The method never bets a side the market gives less than 40% with the margin out, about +150 or longer, however wide the gap. On underdogs our number has not beaten the price over the two seasons it was tested on. The market gives Dallas 15.2%.

ESPN’s injury list for the game, read 15 November 2026 at 04:32 UTC, has five Mavericks out: Daniel Gafford (face), Max Christie (ankle), Dereck Lively II (foot), Tarik Biberovic (heel) and Sergio de Larrea (knee). Boston’s list is empty. The list is not in the rating and does not change the call. Check the lineups before you bet.

The bet risks $750 to win $100. Our number still gives Dallas an 8.9% chance to win. The case is that this risk is smaller than the 15.2% the price implies.

The total and the spread

The total is 217.5, over -110 and under -110. Last season the Celtics’ home games went over 217.5 in 24 of 41, a 58.5% rate. The Mavericks’ road games went over in 31 of 40, a 77.5% rate. Boston’s home games averaged 221.8 points and Dallas’s road games 231.3. Across all 82 games, Boston went over this line 46 times and Dallas 65 times.

Our count puts the over at 68.0%, against 50.0% priced, a gap of 18.0 points toward the over. That count reads last season’s games against today’s line, not the rating. Our method stakes the moneyline only, so this is a lean, not a bet.

The spread is Celtics -14.5 at -109 and Mavericks +14.5 at -111. It opened Celtics -12.5. Last season Boston beat this line at home in 13 of 41 games, and Dallas stayed inside it on the road in 30 of 40. Our count has Celtics -14.5 covering 28.4% of the time against 49.8% priced, a gap of 21.4 points toward Mavericks +14.5.

That is a lean too, and it does not contradict the pick: a Boston win by 14 or fewer fits both. One bet on this game: the Celtics at -750.
