Castle, who spent the 2023-24 college season playing for UConn, is widely expected to be one of the first guards off the board in the draft. He averaged 11.1 points, 4.7 rebounds and 2.9 assists per game in the 2023-24 campaign, and he might be the point guard of the future the Spurs have been looking for. He'd certainly be a long-term upgrade over Tre Jones, who held the starting point guard role toward the end of the 2023-24 campaign.
