National Basketball Association rosters are fluid rosters comprised of fifteen players per team, subject to continuous changes driven by the draft, free agency signings, training camp cuts, and mid-season trades. Front offices meticulously balance max-salary superstars, rotation veterans, and developmental prospects on two-way contracts. Following major summer transactions and rookie acquisitions, teams finalize their official roster constructions ahead of the preseason to prepare for the rigorous eighty-two-game regular-season schedule.
