Stephon Castle's impressive run in the NBA culminated with his winning the Rookie of the Year award, receiving 92 out of 100 first-place votes. This marks the second consecutive year a San Antonio Spurs player has claimed the title, following Victor Wembanyama's victory last season. Castle's development was noteworthy, starting the season as a third option with modest scoring averages. However, under the mentorship of Chris Paul, he emerged as a key player, particularly after the All-Star break, where he averaged 17.8 points, 5.1 rebounds, and 5 assists per game.

In the final voting, Zaccharie Risacher and Jaylen Wells finished second and third, respectively, highlighting a strong rookie class. Castle's journey reflects both resilience and growth, showcasing his defensive skills early on and his evolution into a primary offensive threat. His performance in March, where he averaged 19.5 points with an efficient shooting percentage, solidified his status as a standout rookie.
