The Dallas Mavericks selected Cooper Flagg with the number one pick in this year's NBA draft. Flagg predicted his toughest challenge heading into his first season before his name was called by Adam Silver on June 25. He was introduced by the Mavs two days later and will wear the No. 32 jersey.

The Mavericks took Duke forward Cooper Flagg with the No. 1 pick in the NBA draft Wednesday night, selecting the 18-year-old from Maine who was the college player of the year in his lone season.

The Dallas Mavericks have signed No. 1 overall draft pick Cooper Flagg to his four-year rookie contract, and a person with knowledge of the agreement said Wednesday the club is bringing back guard Dante Exum on a one-year contract.
