Castle was selected by the Spurs with the No. 4 overall pick in the 2024 NBA Draft. A key piece in UConn's run to the national championship this spring, Castle will now team up with Victor Wembanyama in San Antonio. Checking in at 6-foot-6 with a 6-foot-9 wingspan, Castle has excellent size and is capable of playing both guard spots, as well as defending on the wing. Defense was his calling card at UConn, but the belief is that he'll be able to show off an expanded offensive package at the NBA level. Shooting is a major question mark for Castle, as he knocked down just 26.7 percent of his three-point attempts for the Huskies as a freshman. In Summer League, he averaged 17.3 points and 1.3 threes on 37/25/67 shooting, 5.7 rebounds, 4.0 assists, 1.3 steals and 2.3 turnovers in 25.5 minutes. He was aggressive offensively and played with physicality but didn't answer any questions about his shooting. For fantasy, there is concern about Castle's role in the offense and how many minutes he'll get. He's competing with Chris Paul, Tre Jones, Devin Vassell, Keldon Johnson, and to some extent, Harrison Barnes and Jeremy Sochan. Castle's lack of floor spacing complicates an already-squeezed court for Wembanyama.
