Points Prop Today – De'Aaron Fox 15+ Points

De'Aaron Fox is averaging 15.9 points per game, already clearing this 15-point line, and he is doing it efficiently at 58.2% from the field.

He is also a primary creator at 6.4 assists per game, which keeps him involved in nearly every San Antonio possession and gets him downhill against a Dallas defense that allows 112.3 points per game, 14th in the NBA.

Dallas gave the ball away 21 times in the Oct. 24 meeting, and that kind of sloppy play turns into early-offense looks for the Spurs' guards.

Only Tobias Harris (calf) and Jayden Quaintance (knee) are listed out for San Antonio, so the starting group stays intact, while Dallas is without center Dereck Lively II to protect the rim.

• If Fox scores 15 or more points: this ticket returns $170.66.
• If he doesn't: the full $100 stake is lost, since Kalshi contracts settle all-or-nothing.

A return of about 1.7x your stake on an efficient guard backing a heavy home favorite.

Points Prop Today – Cooper Flagg 25+ Points

Cooper Flagg is averaging 25.2 points per game, 11th in the NBA, and 26.3 over his last five, so this 25-point line sits right at his scoring pace.

Dallas leans on him whenever its guards are limited, and with Max Christie and Dereck Lively II out and Kyrie Irving on a managed workload, his usage should stay high.

He also impacts the game on both ends, averaging 6.5 assists and 2.5 steals, and those steals turn into easy transition points.

He missed the first meeting with a shoulder sprain, so this is his first look at the Spurs, and Dallas needs him to create against a guard group that forced 21 turnovers.

• If Flagg scores 25 or more points: this ticket returns $172.24.
• If not: the $100 stake is gone entirely.

A return of about 1.7x your stake on Dallas's go-to scorer.

Points Prop Today – Victor Wembanyama 30+ Points

Victor Wembanyama is averaging 25.7 points per game, 10th in the NBA, and he scored 31.2 per game across the five-game stretch from Oct. 23 to 31.

His path to 30 runs through Dallas's interior. Dereck Lively II is out, which leaves Daniel Gafford as the main rim presence, and Wembanyama's length gives him an edge over any Dallas big.

He is also a threat from deep at 1.6 made threes per game, so he does not need post touches alone to reach a big number.

He scored 23 in the first meeting, and the risk is a blowout, as in Monday's win over Utah when he scored just 12.

• If Wembanyama scores 30 or more points: this ticket returns $260.44.
• If not: the full $100 stake is a total loss.

A return of about 2.6x your stake on the league's 10th-leading scorer.

Points Prop Today – Kyrie Irving 25+ Points

Kyrie Irving is averaging 21.4 points in five appearances and makes 3.2 threes per game, 15th in the NBA, so a hot shooting night can push him past 25 quickly.

He is shooting 52.7% from the field, and with Max Christie out, Dallas needs scoring from its guards against a Spurs team that is 11.5-point favorites.

Irving was not on Dallas's initial injury report after resting his left knee in Monday's loss to Sacramento, and he is working back toward a full workload after missing all of last season with a torn ACL.

The managed minutes are why this is the longest price on our board, but when he plays Dallas leans on him, and the Mavericks beat a short-handed Oklahoma City team 120-96 with him in the lineup.

• If Irving scores 25 or more points: this ticket returns $317.93.
• If not: the $100 stake is lost entirely.

A return of about 3.2x your stake, the longest price among our picks.

Three-Point Prop Today – Cooper Flagg 2+ Three-Pointers

Cooper Flagg is making 1.2 threes per game, so 2+ asks for a modest step up, and his 25.2 points per game give him plenty of attempts to get there.

With Max Christie out, Dallas loses one of its perimeter options, which shifts more of the perimeter looks to Flagg.

San Antonio's opponents are making 12.0 threes per game against it, so the Spurs are giving up chances from deep.

Dallas's best route to staying close is shooting, and it makes 48.3% of its field goals.

• If Flagg makes two or more threes: this ticket returns $209.45.
• If not: the full $100 stake is lost.

A return of about 2.1x your stake on Dallas's lead creator.

Three-Point Prop Today – Julian Champagnie 3+ Three-Pointers

Julian Champagnie averages 3.1 made threes per game, 17th in the NBA, so 3+ sits right at his average.

He is one of San Antonio's main scorers off the bench alongside Keldon Johnson, and with Tobias Harris out, his minutes should stay steady.

The Spurs' three-guard starting group pressures the rim, and Champagnie is the kind of shooter those drives tend to find on the perimeter.

San Antonio is also a heavy favorite, which gives its bench shooters a chance to stay on the floor and keep firing.

• If Champagnie makes three or more threes: this ticket returns $218.68.
• If not: the $100 stake is a total loss.

A return of about 2.2x your stake on a shooter who is already hitting this number.

Assists Prop Today – Stephon Castle 6+ Assists

Stephon Castle is averaging 5.0 assists per game, so 6+ asks for one more pass than usual.

He gets plenty of chances, since Dallas turns the ball over 17.0 times per game and gave it away 21 times in the first meeting, which turns into the transition looks that produce assists.

San Antonio averages 27.4 assists per game as a team, and Castle is one of three guards driving that ball movement alongside De'Aaron Fox and Dylan Harper.

He is also making 2.4 threes per game, which keeps defenders honest and opens passing lanes when he attacks.

• If Castle dishes six or more assists: this ticket returns $173.23.
• If not: the full $100 stake is lost entirely.

A return of about 1.7x your stake on a creator facing a turnover-prone defense.

Assists Prop Today – Naji Marshall 4+ Assists

Naji Marshall is averaging 6.0 assists and 11.5 points per game in four appearances, so 4+ sits well below his current average.

With Max Christie out and Kyrie Irving on managed minutes, Dallas needs secondary playmaking, and Marshall is the one filling it.

Dallas averages 25.9 assists per game as a team, and Marshall's role as a connector keeps the ball moving.

He also averages 1.8 steals, which turns into transition chances where assists come easily.

• If Marshall dishes four or more assists: this ticket returns $209.50.
• If not: the $100 stake is gone entirely.

A return of about 2.1x your stake on a number well under his average.

Rebounds Prop Today – Kyrie Irving 4+ Rebounds

Kyrie Irving is averaging 3.4 rebounds per game, so 4+ asks for slightly more than his average.

Dallas is without Dereck Lively II and ranks 20th in the NBA at 42.4 rebounds per game, so its guards have to crash the glass.

With Victor Wembanyama protecting the rim, Dallas is pushed toward jump shots, and long rebounds off missed threes tend to fall to guards like Irving.

He is not on the injury report, though his managed minutes are the risk on this number.

• If Irving grabs four or more rebounds: this ticket returns $179.87.
• If not: the full $100 stake is lost.

A return of about 1.8x your stake on a number just above his average.

Rebounds Prop Today – Victor Wembanyama 12+ Rebounds

Victor Wembanyama is fifth in the NBA at 10.7 rebounds per game, so 12+ asks for a slightly bigger night than his average.

Dallas is without Lively, and P.J. Washington (7.7) and Daniel Gafford (7.0) are its top rebounders, with no one on the roster who matches Wembanyama's length.

Dallas shoots just 33.1% from three, 21st in the NBA, which leaves plenty of missed shots to rebound, and the Spurs are eighth in the league at 46.7 rebounds per game.

He also pulled down 11 rebounds in Monday's win over Utah, so the number is within reach.

• If Wembanyama grabs 12 or more rebounds: this ticket returns $197.04.
• If not: the $100 stake is lost entirely.

Nearly a 2x return on the league's fifth-leading rebounder.
