NCAAB Totals and Picks for the Underdog Promo

If you are looking to take advantage of tonight’s slate, the player prop market offers several high-scoring projections. Here are the five players with the highest points over/under lines for tonight’s matchups:

  • AJ Dybantsa, BYU Cougars (vs. Texas Longhorns) – 27.5 Points
  • Robert Wright III, BYU Cougars (vs. Texas Longhorns) – 19.5 Points
  • Dailyn Swain, Texas Longhorns (vs. BYU Cougars) – 18.5 Points
  • Henri Veesaar, North Carolina Tar Heels (vs. VCU Rams) – 18.5 Points
  • Paulius Murauskas, Saint Mary’s Gaels (vs. Texas A\&M Aggies) – 18.5 Points

All eyes should be on the West Region clash at the Moda Center. BYU freshman star AJ Dybantsa, a consensus AP First-Team All-American and projected No. 1 NBA Draft pick, draws an astronomical 27.5-point total. I’m watching to see how he exploits a fatigued Texas squad fresh off their First Four win.

Texas will rely heavily on Dailyn Swain (18.5 points) in a key matchup to get physical and slow Dybantsa down, especially since the 23-11 Cougars are lacking depth after losing senior guard Richie Saunders to an ACL tear.

Out in the South Region at the Bon Secours Wellness Arena in Greenville, North Carolina’s 7-foot junior center Henri Veesaar is the clear offensive focal point with Caleb Wilson sidelined for the tournament. Veesaar is coming off a massive 28-point, 17-rebound performance.

Finally, at the Paycom Center in Oklahoma City, we have a fascinating clash of styles. Saint Mary’s junior forward Paulius Murauskas is a real chance to anchor your entries tonight as he looks to eclipse his 18.5-point total against the Texas A\&M Aggies.

Steps to Register with the Underdog Promo Code

If you are a new user ready to step up to the window and meet the necessary age and regional requirements, unlocking your bonus is quick and easy. Click here and follow these simple steps to claim your reward:

  • Create an Account: Register for a new account by providing your standard personal information. You must enter promo code SOUTH during the sign-up process to ensure you are eligible for the reward.
  • Make a Deposit: Add funds to your new account by depositing at least $5 using one of the secure payment methods provided.
  • Submit Your First Entry: Play a minimum $5 entry on the platform. Once your entry is submitted, it will instantly activate your $50 in bonus entries.

When building your entries for tonight’s college basketball slate, you don’t need to hit a complex trifecta to see a real return. You have two different playstyles to choose from:

  • Standard Entry: By selecting 2+ picks, you can build a Standard entry. This option will trigger the largest potential payout, but keep in mind that all legs must hit for your entry to win.
  • Flex Entry: If you want a little bit of insurance—and we know how wild March can get—you can opt for a Flex entry, which requires 3+ picks. With a Flex entry, you can still receive some winnings even if one leg is incorrect.
