ATLANTA — The Atlanta Hawks have officially re-signed All-Star Paul Millsap and finalized a trade for reserve center-forward Tiago Splitter. Millsap, a two-time Eastern Conference All-Star, was an unrestricted free agent before agreeing last week to a three-year, $58.9 million deal contract. In his second year with the Hawks last season, Millsap helped the team win 60 games for the first time and reach the Eastern finals.
