March Madness Player Props via Underdog

If you are looking to put your Underdog promo to use and find an analytical edge, tonight’s slate features some incredibly high scoring projections. Here are five players to look into for some of these March Madness games today:

• Dominique Daniels Jr. (California Baptist Lancers @ Kansas Jayhawks): 21.5 Points
• Darryn Peterson (Kansas Jayhawks vs. California Baptist Lancers): 21.5 Points
• Zuby Ejiofor (St. John’s Red Storm vs. Northern Iowa Panthers): 17.5 Points
• Flory Bidunga (Kansas Jayhawks vs. California Baptist Lancers): 12.5 Points
• Bryce Hopkins (St. John’s Red Storm vs. Northern Iowa Panthers): 12.5 Points

We’ve seen time and time again that guard play dictates March, and tonight’s slate is headlined by a 9:45 p.m. ET showdown between the California Baptist Lancers and the Kansas Jayhawks. California Baptist guard Dominique Daniels Jr. enters the contest tied for the highest scoring projection of the evening at 21.5 points. The 5’10” dynamo has been a consistent bucket all season, averaging 23.2 points per game, and he will be matching shots with Kansas freshman standout Darryn Peterson. Peterson is finally fully healthy after dealing with minutes restrictions and boasts an aggressive 21.5-point total of his own. Both guards are heavily favored to carry the offensive load in this clash, while Kansas big man Flory Bidunga (12.5 points) provides an intriguing secondary option on the glass.

Earlier in the evening, at 7:10 p.m. ET, the St. John’s Red Storm will lean on their experienced frontcourt against a defensively sound Northern Iowa Panthers squad. Senior forward Zuby Ejiofor, the Big East Player of the Year, is posted at a healthy 17.5-point line. He will be looking to control the interior alongside graduate forward Bryce Hopkins, who is projected for 12.5 points after battling back from a prior ACL injury. It does stand to reason that whether you are looking to stack Peterson and Daniels in a potential shootout or back the St. John’s frontcourt duo, these lines offer excellent building blocks and underlying value for your Underdog entries tonight.

How to Activate the Underdog Promo Code BROAD

Getting started and claiming your Underdog bonus is a quick and straightforward process. To unlock your bonus entries, follow these simple steps:

1. Register Your Account: Create and register a new account by providing standard personal information. During the sign-up process, ensure you enter promo code BROAD to qualify for the promotion. (Note: You must be a new user and meet all local age and region requirements).

When building your entry, Underdog offers two distinct ways to play depending on your risk tolerance:
