After playing an immense part in a national championship run, UConn freshman guard Stephon Castle is entering the 2024 NBA draft, he told ESPN on Friday.

Castle — No. 9 on ESPN’s list of Top 100 prospects — is one of the fastest rising players on NBA draft boards and is expected to push toward the top of the lottery with the momentum of a dominant performance in the Huskies’ NCAA title season.

Castle has selected agents Joe Smith and Thad Foucher of Wasserman for his player representation, he said.

At first glance, Castle’s allure to the NBA is readily apparent. He possesses an elite physical profile at 6-foot-6 — long arms and a chiseled 215-pound frame.

Castle’s a big guard who plays with unique pace. He operates at alternating speeds, flashes intriguing court vision and creativity with his passing off of the live dribble. He developed into one of the best defenders in college basketball, ordinarily tasked with slowing down opposing team’s best player. Castle used his length, frame and quickness to hound opponents with intense ball pressure on the Huskies run through March Madness.
