The Atlanta Hawks have agreed to a five-year, $207-million designated rookie maximum extension, ESPN's Adrian Wojnarowski.
Young, 22, led the Hawks to the Eastern Conference Final in his third season, averaging 25.3 points over 63 games last season and 28.8 points in 16 playoff games.
The fifth-overall pick in the 2018 NBA Draft, Young has helped turn the Hawks from a 20 win team in 2019-20 to a 41 win team last season. He leads a core that includes fellow rising stars John Collins and Clint Capela.
After a surprising run to the third round of the playoffs, the Hawks will enter the 2021-22 season as a favourite in the Eastern Conference. Now that their main star is locked in long-term, the team can focus on rounding out the roster to become a consistent contender.
