Blake Griffin praises Mavericks rookie Cooper Flagg as a rare complete player, fueling sky-high expectations in Dallas.

The Dallas Mavericks are expecting No. 1 overall pick Cooper Flagg to become a contributor for a winning team right away. ESPN insider Zach Kram explains how tall a task it is for Flagg to be thrown into the fire immediately.

NBA Draft on SI's Derek Parker profiles Flagg as a player with a "great frame, solid athleticism and fluid movement as a combo forward" — one who will work with his frontcourt teammates to score off pick-and-roll plays and fit strongly into the team's defensive setup.
