With the NBA Cup in the rearview and the New York Knicks freshly crowned, though they won't raise a banner, Friday’s Dec. 19 slate feels like the first full night of action in a while. We’re back to multiple games, multiple windows and plenty of betting angles to sort through.

Whether you’re chasing value on spreads, looking for the best NBA player props today or building NBA parlay picks today from your favorite stars, this card offers a nice mix of heavyweight matchups and underdog spots to consider across sports betting apps and associated sportsbook promotions.

Game Lines

New York Knicks (-5.5) vs Philadelphia 76ers (-105)

🏀 Odds via BetMGM 📈

New York’s physical defense on the wing can make life tough on Philadelphia’s scorers, especially when the Knicks switch and crowd driving lanes. With Jalen Brunson running the show and multiple reliable options around him, this shapes up as a spot where the Knicks can gradually pull away and cover a two-possession number at home.

Miami Heat (+6.5) vs Boston Celtics (-110)

🏀 Odds via bet365 📈

Boston’s ceiling is obvious, but Miami tends to drag games into a more physical, grind-it-out style that keeps things closer than the spread suggests. With the Heat’s veteran core able to slow tempo and generate efficient looks through half-court execution, grabbing nearly seven points gives you plenty of breathing room, even if the Celtics control most of the night.

Chicago Bulls (+7.5) vs Cleveland Cavaliers (-115)

🏀 Odds via BetMGM 📈

Chicago leans on size and playmaking on the perimeter, which helps them avoid long scoring droughts and keeps them competitive against more talented teams. Cleveland’s frontcourt has advantages, but if the Bulls take care of the ball and hit enough threes, this spread is big enough for them to hang inside the number as two teams who are struggling clash.

San Antonio Spurs (-2.5) vs Atlanta Hawks (-105)

🏀 Odds via Caesars Sportsbook 📈

San Antonio’s guard play and three-level scoring from its stars give the Spurs a more reliable offensive base than Atlanta right now. If they can keep the Hawks out of transition and win the free-throw battle, a short spread under three points is very playable.

Player Props

OG Anunoby over 5.5 rebounds (-139)

🏀 Odds via Caesars Sportsbook 📈

Anunoby’s strength and wingspan let him guard up a position and still clean the glass, especially on long rebounds. In a game where both teams will be firing from outside, he should find enough opportunities to come down with six or more boards.

Tyrese Maxey over 6.5 assists (+115)

🏀 Odds via Caesars Sportsbook 📈

Maxey’s growth as a playmaker shows in how comfortable he is manipulating pick-and-roll coverages and hitting shooters in rhythm. Against an aggressive Knicks defense that loves to help and recover, his ability to make quick reads should create a path to seven or more dimes.

Norman Powell over 22.5 points (-112)

🏀 Odds via BetMGM 📈

Powell is a professional bucket-getter who thrives attacking closeouts, living at the rim and drawing contact. In an up-tempo matchup where he’s likely to see heavy minutes and plenty of touches, this number is reachable if his jumper is even average because of volume.

Josh Giddey over 8.5 assists (-115)

🏀 Odds via Caesars Sportsbook 📈

Giddey is at his best when he has the ball in his hands and shooters spaced around him, and Chicago leans on him to organize the offense. With his size allowing him to see over the defense and fire cross-court passes, nine or more assists is well within reach if teammates knock down open looks.

Nickeil Alexander-Walker over 3.5 rebounds (+105)

🏀 Odds via bet365 📈

Alexander-Walker is an active guard who crashes down from the perimeter and isn’t shy about mixing it up on the glass. In lineups with multiple shooters, he often ends up near the elbows on defense, putting him in a great spot to grab four or more rebounds.

Devin Vassell over 2.5 made threes (+115)

🏀 Odds via BetMGM 📈

Vassell’s volume from deep is solid, and his role as a floor spacer around on-ball creators keeps him involved in most half-court sets. If the Spurs’ stars consistently collapse the defense, Vassell should see enough clean catch-and-shoot chances to hit three or more from beyond the arc.

Jalen Williams over 18.5 points (-105)

🏀 Odds via Caesars Sportsbook 📈

Jalen Williams is a three-level scorer who punishes mismatches and plays well off teammate gravity. With his ability to get downhill, hit pull-ups and score in the mid-post, he has several avenues to a 20-point night as long as he gets his normal workload.

Naz Reid over 1.5 made threes (-176)

🏀 Odds via BetMGM 📈

Naz Reid stretches the floor as a big who is very comfortable stepping out to the perimeter, especially in pick-and-pop situations. With defenses focused on protecting the paint against his frontcourt partner, Reid should see multiple open looks from deep, making two made threes a realistic expectation.

Today’s Best Parlay

🏀 Combined Parlay Odds: +1141 (via bet365) 📈

Castle’s downhill aggression and willingness to attack the rim should translate into both free throws and easy finishes if he keeps pressure on Atlanta’s guards. Wembanyama is a matchup nightmare who can score over the top of smaller defenders and stretch bigs out to the perimeter, giving him multiple ways to clear his number. Fox brings elite speed and pull-up shooting, and when he’s living in the paint and at the foul line, crossing 20 points is well within his standard range. Johnson rounds out the parlay as a big wing scorer who can run the floor, cut for easy buckets and create his own shot when possessions stall, giving this four-leg build real upside if the game turns into a high-possession shootout.
