The Atlanta Hawks have re-signed Shelvin Mack.

"Shelvin has proven himself to be an excellent fit in our program,” Ferry said. “On the court, he plays well within our system and possesses a toughness and level of unselfishness that we truly value," Ferry said. "At 24, he is still a young player with the type of work ethic that can allow him to continue to keep getting better." 

In 73 games for the Hawks last season (11 starts), Mack averaged 7.5 points, 3.7 assists (second on the team) and 2.2 rebounds in 20.4 minutes while ranking seventh in the NBA in assist/turnover ratio (3.04).

Lamar Patterson has signed with Tofas, a Turkish club, for the 2014-15 season.

Patterson was the second round choice of the Atlanta Hawks in this year's NBA draft.

“Lamar is in a good position to continue his development while playing meaningful minutes for a strong professional program next season," Danny Ferry said in a statement on Tuesday. "We have a great respect for the international game and will be closely monitoring Lamar’s progress with Tofas.”

The Atlanta Hawks have named Neven Spahija an assistant coach.

“Neven is one of the most successful coaches in Europe and we’re thrilled to add him to our staff,” said Hawks Head Coach Mike Budenholzer. “As an organization, we have great respect for international basketball and we will benefit tremendously from his perspective and his wealth of experience.”

Spahija, a Croatia native and former Croatian Coach of the Year with nearly 30 years international coaching experience, was most recently head coach of Cibona Zagreb (Croatia) last season. From 2010-12, Spahija led Fenerbahce Ulker (Turkey), winning a Turkish Basketball League and Turkish Cup championship in 2010-11 after directing the club to a 27-3 regular season mark.

Mike Scott has agreed upon a three-year, $10 million deal to re-sign with the Atlanta Hawks.

Scott is a restricted free agent this offseason.
