DFS Pick’em Options for NBA: Suns-Mavericks
One of my favorite things about Underdog Fantasy is that there are team and player pick’em DFS contests for the NBA. With player picks, you must select a minimum of two players from at least two NBA teams and then select “Higher” or “Lower” on their stat lines.
The team picks, on the other hand, are similar to betting lines, as you can find moneylines, points totals, spreads, and more.
With that in mind, here are my top team and player lineup picks for Suns @ Mavericks on Wednesday, November 12, 2025:
Team picks
- Dallas Mavericks - Lower than 110.5 points
- Dallas Mavericks - To cover the spread
- Dallas Mavericks - To win on the moneyline
Player picks
- Devin Booker (Suns) - Higher than 27.5 pts
- P.J. Washington (Mavericks) - Higher than 7.5 reb
- Cooper Flagg (Mavericks) - Lower than 1.5 Stl
