June 25 (UPI) -- Projected No. 1 overall pick Cooper Flagg said he has a "positionless" mentality, is open to multiple roles and prioritizes improvement heading into the first round of the 2025 NBA Draft on Wednesday in Brooklyn.

The first round will start at 8 p.m. EDT and air on ABC, ESPN and the ESPN app. Flagg, Rutgers stars Dylan Harper and Ace Bailey, Baylor's V.J. Edgecombe and several of Flagg's former Duke teammates, including Kon Knueppel and Khaman Maluach, are among the projected Top 10 picks.

"It's incredible to be her and be in these moments," Flagg told reporters Tuesday. "This is stuff I've dreamed about since I was a little kid. I think being here is surreal. I don't think it's really set in yet.

"I'm just trying to go through each moment and enjoy it."

The Dallas Mavericks are widely expected to select Flagg to open Wednesday's first round. The former Duke sensation -- who earned multiple National Player of the Year honors as a freshman -- is set to join a lineup led by All-Stars Kyrie Irving, Anthony Davis and Klay Thompson.
