Jalen Brunson's eligibility for the Supermax contract hinges on the terms of his current contract. If he signs a four-year deal that includes a player option for the fourth year, which is a common and reasonable arrangement in the NBA, he would enter unrestricted free agency in 2028. At that point, he would have completed ten seasons in the league, thus qualifying him for the veteran Supermax contract. This type of contract is designed to reward players who have demonstrated significant contributions to their teams over a decade, allowing them to secure a lucrative deal based on their experience and performance. Therefore, if Brunson's career continues on its current trajectory, he could potentially command a substantial Supermax contract in 2028, reflecting his growth and value as a player in the league.
