Knicks vs Spurs NBA Cup Finals: Building Winning Pick’em Slips on Underdog

Tonight, we have New York (18-7) vs San Antonio (18-7) at T-Mobile Arena in Las Vegas. Knicks -2.5, total 234.5. Let’s dig into more important information.

NBA Cup Finals Game Info

  • Game: San Antonio Spurs (18-7) vs New York Knicks (18-7)
  • Time: 8:30 PM ET, Tuesday, December 16, 2025
  • Location: T-Mobile Arena, Las Vegas
  • TV: Amazon Prime Video
  • Spread: Knicks -2.5
  • Moneyline: Spurs +120, Knicks -140
  • Total: 234.5

What’s at stake: The NBA Cup championship trophy, bragging rights, and $500,000 per player for the winning team ($200,000 for the runner-up). This game doesn’t count in the regular season standings, but the competition is real.

How To Use Underdog Welcome Offer

Here’s the thing: Underdog lets you build Higher/Lower pick’em slips where you decide if a player will go over or under a stat total. These work exactly like player props at sportsbooks, but with a DFS-style twist.

How it works:

  • You pick if a player goes HIGHER or LOWER than their stat line
  • Single-entry picks pay 1x your entry (e.g., $100 entry = $100 profit)
  • Stack multiple picks together for multiplied payouts (2 picks = 3x, 3 picks = 6x, etc.)

Example for tonight: “Knicks control the paint, OG Anunoby dominates the glass, Jalen Brunson facilitates.”

How that builds on Underdog:

  • OG Anunoby HIGHER 4.5 rebounds
  • Jalen Brunson HIGHER 6.5 assists

That’s a coherent narrative, not random props. Each pick feeds the same story.

Best Underdog Props Tonight: Bonus Code Plays

Let’s jump into the good stuff!

OG Anunoby HIGHER 4.5 Rebounds

This is the anchor prop for any Knicks pick’em slip tonight.

OG Anunoby has been dominating the glass in the Knicks’ recent stretch. Over his last 5 games, he’s averaging 10 rebound chances per game—that’s elite volume for a wing player.

OG’s Recent Rebound Performance:

  • Dec 13 vs Orlando: 6 rebounds (40 minutes, NBA Cup semifinals)
  • Dec 9 @ Toronto: 6 rebounds
  • Dec 7 vs Orlando: 7 rebounds
  • Nov 9 vs Brooklyn: 8 rebounds
  • Nov 5 vs Minnesota: 8 rebounds

He’s cleared 4.5 rebounds in every single game in his last 5. Against a Spurs team that attacks the paint with Victor Wembanyama and Jeremy Sochan, the Knicks will need OG crashing the glass hard.

Stephon Castle HIGHER 17.5 Points

Here’s where sharp bettors are moving: Stephon Castle has seen massive usage since returning from injury for the Spurs.

Castle, San Antonio’s rookie guard, has been cooking lately. His usage rate has skyrocketed in recent games, and he’s expected to play heavy minutes in tonight’s NBA Cup Finals with Wembanyama commanding double-teams.

Castle’s Recent Scoring:

  • Averaging 15.1 PPG on the season
  • Posted 26 points on Nov 2 vs Phoenix
  • Posted 22 points on Oct 27 vs Toronto
  • Huge free-throw rate: 4.6 FTA per game (gets to the line consistently)

Against a Knicks defense that ranks middle of the pack in perimeter defense, Castle should see opportunity. If Wembanyama draws help defense in the paint, Castle gets clean looks from three and driving lanes.

Victor Wembanyama Props on Underdog

Wemby just returned from a 12-game absence due to a left calf injury and immediately went off in the semifinals: 22 points, 9 rebounds, 2 blocks in just 21 minutes against OKC.

The beautiful thing about playing on Underdog is that you DO NOT have to make a decison on anything Wemby-related.

Jalen Brunson Props on Underdog

Brunson has been elite in the NBA Cup run. He dropped a vintage performance in the semifinals against Orlando and is the Knicks’ primary offensive engine.

Brunson’s Season Stats:

  • Averaging 25+ PPG and 7+ APG
  • Elite free-throw rate
  • Thrives in big-moment games

He’s been such a great scorer that I’m leaning lower than 6.5 assists.

Good luck, and take advantage of this Underdog Promo Code!
