The Hawks completed several offseason moves with the official signings of free agents Kris Humphries, Jarrett Jack and Malcolm Delaney and first-round draft picks Taurean Prince and DeAndre’ Bembry.

Humphries, Jack and Delaney had previously agreed to deals. Prince (No. 12 overall) and Bembry (No. 21) signed their rookie contracts.

The five additions join Dwight Howard and Kent Bazemore who signed their contracts and were announced by the team earlier this week.

Humphries, 31, signed a one-year, $4 million deal to return to the Hawks after he was a late-season acquisition. In 21 games, in which the Hawks went 15-6, he averaged 6.4 points and 3.4 rebounds in 14.0 minutes. He was acquired on March 1 after his contract was bought out by the Suns shortly after he was traded from the Wizards.

“We’re thrilled to be able to bring Kris back to Atlanta,” Hawks president of basketball operations/head coach Mike Budenholzer said in a statement. “He quickly fit in with our team last season and played an important role on the court and in the locker room.”

Jack, 32, signed a one-year, $1.6 million veteran minimum contract. He was waived by the Nets this summer and is rehabbing from a torn ACL of the right knee. Jack averaged 12.8 points, 7.4 assists, 4.3 rebounds and 1.1 steals in 32.1 minutes in 32 games before his injury.

“Jarrett brings a wealth of knowledge and experience to our backcourt,” Budenholzer said. “His leadership and versatility will be important to our team.”

Delaney, 27, played five seasons overseas after going undrafted out of Virginia Tech. In 301 games, he averaged 14.0 points, 4.2 assists, 3.6 rebounds and 1.1 steals in 30.3 minutes.

The signings give the Hawks a roster of 16 players under contract. Undrafted free agent Matt Costello also signed a contract with the Hawks and will attend training camp. The Hawks do not have to get down to the league maximum of 15 players until October before the start of the 2016-17 regular season.
