Žalgiris's preparation for the 2016–17 season began during the 2016 LKL finals, when the club signed point guard Léo Westermann to replace the departing Jerome Randle. After the season, Pocius, Hanlan, Vougioukas, and long-time Žalgiris players Siim-Sander Vene and Kaspars Vecvagars, all left the team, while Žalgiris chose to retain the services of Seibutis and Motum. Žalgiris also re-signed Edgaras Ulanovas. Head coach Jasikevičius was pursued by FC Barcelona Lassa, but decided to remain with Žalgiris. To correct the previous season's lack of a good shooter, Žalgiris signed Kevin Pangos; the team was loaned Augusto Lima from Real Madrid to replace Vougioukas at center. Žalgiris also signed the returning Artūras Milaknis to a 3-year deal. German prospect Isaiah Hartenstein was scheduled to make his professional debut after being signed in the previous season. In August, Žalgiris signed Antanas Kavaliauskas, the captain of Lietuvos Rytas who had previously promised to never play for Žalgiris; Kavaliauskas apologized to fans after the signing was announced.
