Trae Young, Kevin Huerter and Omari Spellman signed their Hawks contracts on Sunday.

As first-round picks the players’ contract terms and salaries are dictated by the rookie scale. They received two-year guaranteed contracts with team options for the 2020-21 and 2021-22 seasons. The Hawks signed all three players for 120 percent of the rookie scale, the maximum allowable, according to a person familiar with the contracts.

Young, the No. 3 overall pick, will receive $6.5 million in 2018-19 and $7.6 million in 2019-20. His option salaries are $8 million and $10.1 million.

Huerter, the No. 19 overall pick, will receive $2.2 million in 2018-19 and $2.6 million in 2019-20. His option salaries are $2.7 million and $4.2 million.

Spellman, the No. 30 overall pick, will receive $1.6 million in 2018-19 and $1.9 million in 2019-20. His option salaries are $2 million and $3.6 million.

Teams that hold the rights to a player with a rookie-scale contracts can extend a qualifying offer after the fourth season. That makes the player a restricted free agent and the team with his rights can match any contract the player signs with a another team.
