NBA Markets for the Underdog Promo Code
We have a unique landscape tonight with significant injuries reshaping the lines. With stars like Stephen Curry, Joel Embiid, and Ja Morant sidelined, the usage rates for the remaining stars are going through the roof. This creates high-volume opportunities for players carrying the offensive load.
Here are the guys I’m eyeing with the highest statistical scoring ceilings for tonight’s matchups based on season averages:
Shai Gilgeous-Alexander (Oklahoma City Thunder vs. Golden State Warriors)
- Stat to Watch: 31.7 PPG (Season Average)
Anthony Edwards (Minnesota Timberwolves vs. Orlando Magic)
- Stat to Watch: 29.5 PPG (Season Average)
Tyrese Maxey (Philadelphia 76ers vs. Atlanta Hawks)
- Stat to Watch: 28.9 PPG (Season Average)
Kawhi Leonard (LA Clippers vs. Memphis Grizzlies)
- Stat to Watch: 27.9 PPG (Season Average)
Giannis Antetokounmpo (Milwaukee Bucks vs. Utah Jazz)
- Stat to Watch: 27.6 PPG (Season Average)
Matchup Highlights
If you are looking for a mismatch to exploit, look no further than Giannis Antetokounmpo. The “Greek Freak” is averaging a massive 27.6 points and 9.9 rebounds, and tonight he faces a Utah Jazz frontcourt that has been absolutely decimated by injuries. With Lauri Markkanen, Walker Kessler, and Jusuf Nurkić all out, Utah lacks the size to protect the rim. The Jazz are already allowing a league-high 125.2 points per game; without their bigs, Giannis should feast in the paint.
In Philadelphia, Tyrese Maxey is shouldering the entire offense with Joel Embiid out. While the Sixers are struggling to find wins, Maxey’s volume is undeniable. He faces an Atlanta Hawks defense that is surrendering 117.3 points per game, giving him a real chance to light up the scoreboard. Meanwhile, Shai Gilgeous-Alexander continues his MVP-caliber campaign. The Thunder are looking like a legitimate playoff threat, and against a Warriors squad missing Curry and their usual defensive grit, SGA is in a prime spot to dominate.
Finally, keep an eye on Paolo Banchero for some injury-driven value. He has a tough test against Rudy Gobert’s rim protection in Minnesota, but the volume will be there.

Understanding Your Entry Options
When you are ready to use those bonus entries, Underdog gives you two distinct ways to play. It’s important to know the difference so you can manage your risk:
- Standard Entry: This is for when you are feeling confident. It yields the largest potential payouts and requires a minimum of two picks, but all legs must hit for the entry to win.
- Flex Entry: If you want a strategic safety net—which I often recommend for exotic bets—you can “Flex” an entry with three or more picks. This allows you to still receive some winnings even if one leg of your prediction is incorrect, significantly reducing the volatility of the play.
