Luka Doncic, Trae Young, 2018 Rookie Class Set NBA Record $1B in Contract Extensions

The 2018 rookie class set an NBA record for contract extensions after Jaren Jackson Jr.'s four-year, $105 million deal with the Memphis Grizzlies took that draft class over a billion dollars in extension agreements, per ESPN's Bobby Marks.

That number could rise ahead of Monday's 6 p.m. ET deadline for such extensions. The top overall pick in the 2018 NBA draft, Phoenix's DeAndre Ayton, is the most notable member yet to sign an extension.

Here are the extensions that have been signed:

• Luka Doncic, Dallas Mavericks: five years, $207.1 million
• Trae Young, Atlanta Hawks: five years, $172.5 million
• Wendell Carter Jr., Orlando Magic: four years, $50 million
• Mikal Bridges, Phoenix Suns: four years, $90 million
• Shai Gilgeous-Alexander, Oklahoma City Thunder: five years, $172.5 million
• Michael Porter Jr., Denver Nuggets: five years, $172.5 million
• Robert Williams, Boston Celtics: four years, $48 million
• Jaren Jackson Jr., Memphis Grizzlies: four years, $105 million

It remains to be seen if players like Ayton, Collin Sexton, Miles Bridges and Mo Bamba will come to agreements before the deadline. Don't expect 2018 No. 2 overall pick Marvin Bagley III to sign a long-term extension with the Sacramento Kings, however:

The 22-year-old Doncic is the jewel of the 2018 draft class. He was the 2018-19 Rookie of the Year and is a two-time All-Star and two-time first-team All-NBA selection. He was dominant in the 2020-21 season, averaging 27.7 points, 8.6 assists and 8.0 rebounds per game, and heads into the 2021-22 season as one of the front-runners for MVP. 

But all eyes are on Ayton, who helped lead the Suns to the NBA Finals last season, averaging 14.4 points, 10.5 rebounds and 1.2 blocks per game. He has solidified the center position for Phoenix and fits the modern game with his athleticism, though he hasn't had the impact Doncic or Young did on their respective organizations. 

Ayton assuredly is seeking a max extension. The Suns appear to be balking at offering him one. He's trending toward becoming a restricted free agent after the season.
