The free-agent forward is finalizing a three-year, $61.5 million contract with the Atlanta Hawks, his agent, Michael Tellem of CAA Sports, told ESPN's Adrian Wojnarowski. Over the past week, the retooling Thunder have made multiple moves, including sending Chris Paul to the Phoenix Suns, Dennis Schroder to the Los Angeles Lakers, Kelly Oubre Jr. to the Golden State Warriors and Ricky Rubio to the Minnesota Timberwolves, and a trade in which they acquired Al Horford from the Philadelphia 76ers.

Gallinari, 32, is one of the prize free agents of this class because of his unique combination of size and shooting. With the Thunder last season, Gallinari was a vital part of the team's surprising run to the fifth seed in the Western Conference.
