Expert Underdog Picks for March Madness

After you use the Underdog promo code TOPACTION and create an account, it's time for the fun part of making picks. While there is a bounty of games to choose from, I'm honed in on VCU vs. North Carolina for my first pick 'em entry. I made my picks after I read our Action Network expert Jordan Mann's VCU vs. UNC prediction article, which predicts for the No. 6 seed Tar Heels to be upset:

"Over its past 10 games, VCU is shooting 37% from 3, while UNC ranks 227th in 3-point defense, allowing 35.1% from deep. Even if Veesaar has a monster game, as he did against Clemson, UNC is still susceptible to losing this game because of the inconsistency of others stepping up."

With that in mind, here is my Underdog pick 'em entry of VCU vs. North Carolina college basketball DFS picks:

Player	Pick
Henry Veesaar	Lower than 18.5 points
Terrence Hill	Higher than 14.5 points
Seth Trimble	Higher than 14.5 points
Jarin Stevenson	Lower than 10.5 points

• Win 10x when you select Standard Play on my 4-pick entry and get each prediction correct.
• Win 6x when you choose Flex Play and get all four picks right. When three out of four picks hit, you win 1.5x.
