NBA free‑agency opens on June 24, and teams face a glut of big‑money signings. Yet analysts point to a class of specialists who can swing rotations without breaking the bank. Zach Kram highlights six under‑the‑radar names that missed Bobby Marks’ top‑20 list but could add depth and flexibility to any contender.

Undrafted guard Collin Gillespie exploded in 2025‑26, scoring 1,012 points in 80 games with a 46% catch‑and‑shoot 3‑point rate. His 3:1 assist‑to‑turnover ratio and defensive hustle lifted Phoenix’s floor. Advanced metrics place him in the 91st percentile for per‑possession impact, a number that justifies an eight‑figure salary.

John Collins, now an unrestricted free agent after a $125 million deal, offers 40% 3‑point shooting and rim‑finishing prowess, though availability worries linger. Meanwhile, Matisse Thybulle, who posted a 5.6% steal rate last season, remains a defensive cornerstone. Both players could plug gaps for teams seeking plug‑and‑play rotation mates.

Sandro Mamukelashvili’s 39% 3‑point efficiency and 11.2‑point average after a $5.3 million contract signal a breakout big‑man who can stretch floors. De’Anthony Melton, fresh from a career‑high 12.3 points and 1.6 steals per game, will opt out of a $3.5 million option, sharpening the free‑agency market for defensive and three‑point specialists.
