How to Use Your Underdog NBA Promo Tonight

The Philadelphia 76ers hit the road to face the New York Knicks on October 20, 2026, at 7:00 PM ET. At this early stage of the schedule, current regular-season win-loss records and division playoff standings for both the Philadelphia 76ers and New York Knicks are unavailable, but the projection markets are already offering intriguing player data.

76ers vs. Knicks Props & Analysis

  • Joel Embiid (Philadelphia 76ers): 21.5 Points | 7.5 Rebounds | 3.5 Assists
  • Tyrese Maxey (Philadelphia 76ers): 21.5 Points | 4.5 Assists | 3.5 Rebounds
  • Andre Drummond (Philadelphia 76ers): 5.5 Points | 6.5 Rebounds
  • Jalen Brunson (New York Knicks): 27.5 Points | 6.5 Assists
  • Karl-Anthony Towns (New York Knicks): 18.5 Points | 11.5 Rebounds
  • Mikal Bridges (New York Knicks): 14.5 Points | 1.5 3-Pointers Made
  • OG Anunoby (New York Knicks): 16.5 Points | 5.5 Rebounds
  • Josh Hart (New York Knicks): 11.5 Points | 7.5 Rebounds

Looking at the board, Andre Drummond offers some of the most compelling mathematical value for the Philadelphia 76ers. With his consensus rebound projection set at 6.5 and points at 5.5, exceeding these numbers aligns well with his statistical baseline. Over 63 contests in his 2025 season, Drummond maintained historical averages of 6.40 points and an impressive 8.44 total rebounds per game.

While current seasonal statistics to support the rest of the featured players are presently unavailable, Jalen Brunsonโ€™s lofty 27.5-point consensus total implies that a massive offensive workload is projected for the New York Knicks guard. Likewise, Joel Embiid and Tyrese Maxey are slated for heavy usage for the Philadelphia 76ers, with both stars boasting standard consensus lines of 21.5 points. Down low, Karl-Anthony Towns carries the highest rebounding total of the slate at 11.5, indicating the New York Knicks will lean on him heavily to control the glass.

How Underdogโ€™s โ€œKeep Your Millionโ€ Promotion Works

Underdogโ€™s โ€œKeep Your Millionโ€ promotion lets participants answer up to 20 questions, carrying forward the amount they place on the winning side each time:

  1. Pick a Question: Choose a question, such as whether Patrick Mahomes will throw for Higher or Lower than 275 passing yards.
  2. Split Your Million: Use the slider to allocate the pot between Higher and Lower. You can put it all on one side, split it evenly, or choose any allocation; the full amount must be assigned.

  4. Keep Your Winnings: After the result is settled, the amount allocated to the winning side becomes your pot for the next question.

The Keep Your Million promotion is separate from the 50% deposit-match welcome offer. Review Underdog’s current rules for eligibility and complete details before participating.
