DURHAM, N.C. — The Dallas Mavericks select Duke forward Cooper Flagg with the No. 1 pick in the NBA draft.on Wednesday night, quickly adding another franchise-altering player after trading one away last season.

The Mavericks took the Duke forward 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.

Mavericks fans were furious when Dallas traded Luka Doncic to the Los Angeles Lakers on Feb. 1, some immediately threatening to end their support of the team.

But the ones who stuck around may quickly love Flagg, who averaged 19.2 points and 7.5 rebounds while leading Duke to the Final Four.

He joined Elton Brand, Kyrie Irving – who now becomes his teammate, Zion Williamson and Paolo Banchero as Duke players drafted No. 1 since 1999, and he returned the draft to its longtime start with a one-and-done college player.

Flagg averaged 19.2 points and 7.5 rebounds and led Duke to the Final Four. The 6-foot-8 forward topped the Blue Devils in all five major statistical categories and already has proven he has a game that will more than hold up against the pros when he played well last summer during an invite to the U.S. Olympic team’s training camp.

Flagg would also join two other former Duke players on the Mavericks’ team–Kyrie Irving and Dereck Lively II.

Three other top players are expected to be selected during the draft:

Kon Knueppel, forward at Duke

No. 4 pick Kon Knueppel was drafted by the Charlotte Hornets.

The 6-7, 217-pound Knueppel is an efficient scorer who was named ACC Tournament MVP while Flagg was sidelined by injury. Knueppel shot 40.6% on 3-pointers and ranked sixth in Division I by shooting 91.4% at the foul line. The freshman also had 10 games with at least four assists to show potential as a secondary playmaker for a Final Four team.

Khaman Maluach, center at Duke

No. 10 pick Khaman Maluach was drafted by the Houston Rockets and traded to the Phoenix Suns.

With four first-round picks, the Nets could start with a long-term bet on the 7-1, 253-pound South Sudanese big man to hit his potential as a rim-protecting lob threat. Maluach had the combine’s biggest wingspan (7-6 3/4) and showed stretches of capably defending guards on switches in his lone college season. He shot 71.2% largely on dunks and putbacks, so he’ll need time to refine a raw offensive game.

Tyrese Proctor, Duke

Sion James, Duke

Drake Powell, hometown is Pittsboro; guard/forward at North Carolina

The 6-6, 195-pound freshman offers athleticism, outside shooting (37.9% on 3s), and defensive potential. Powell led all combine players in standing vertical leap (37.5 inches, 4+ inches more than anyone else) and max vertical (43.0) to go with a 7-foot wingspan.

The Spurs have the No. 2 pick this year. Then it’s Philadelphia, Charlotte, and Utah.
