A True Shooter: Duncan Robinson
Duncan Robinson doesn’t really do much other than shoot the three, but he’s one of the best in the game at it. After only three seasons in the NBA, he’s shot a career 42% from behind the arc on well over seven attempts per night.
Looking at the 2019-2020 “Bubble Playoffs” when Robinson was a part of an unexpected Miami Heat run to the NBA Finals, he shot 45% from deep on over eight attempts a night.
He doesn't rebound, pass, put the ball on the floor, or play defense particularly well, but the Spurs have other players who can make up for those shortcomings. The Heat will likely do everything in their power to keep him in Miami, but the Spurs can throw a lot of money his way. Granted, I am a little biased because he played for the Michigan Wolverines, but there’s no denying that his presence alone would make the Spurs a better shooting team.
Last season, the Spurs took the fewest three-point shots and the Heat took the 11th most. If Robinson and Patty Mills (who took the most shots from deep for SA) had switched places this past season, the Spurs would have improved to 25th in the league and the Heat would have fallen to 18th. That being said, if the Spurs had retained Mills but replaced Rudy Gay with Duncan Robinson, the Spurs would have skyrocketed to 20th in the league in three-point attempts.
20th in the league is still not great, but it’s certainly a lot better than dead last. By signing Duncan Robinson alone, the Spurs could go from the absolute worst to at least an average team when it comes to three-point shooting.
Robinson doesn’t do much at a high level aside from three-point shooting, but he would ideally be taking over Rudy Gay’s roster spot, and aside from three-point shooting their numbers are actually comparable. Robinson's much higher level of shooting would make the swap well worth the potential cost.
