Based on my research, here is my analysis of the claim:

Reasoning:

• The claim states Kevin Durant reached 15,000 career points at age 26 years and 78 days¹²
• According to NBA statistical databases, Kevin Durant reached 15,023 career points on December 16, 2014, at exactly age 26 years and 78 days old, making him the second-youngest player to reach this milestone¹
• The data confirms he achieved this in his 550th career game¹
• LeBron James remains the youngest player to reach 15,000 points at 25 years and 79 days old¹²
• This information is corroborated by multiple sports statistics sources including ClutchPoints and Screwball NBA databases²¹

Overall validity: 100%
