The Bulls tweeted a welcome message in announcing the deal about a month after the two sides reached an agreement.
The 36-year-old Dragic has averaged 13.7 points and shot 36.2% on 3-pointers over 14 seasons with Phoenix, Houston, Miami, Toronto and Brooklyn. From Slovenia, he made an All-Star team with the Heat during the 2017-18 season and helped them advance to the 2020 NBA finals.
Dragic averaged 7.5 points while shooting 25.4% from beyond the arc last season for Toronto and Brooklyn. Though the Bulls ranked fourth in the NBA in 3-point accuracy, they were last in attempts.
