2) D'Angelo Russell
Los Angeles Lakers starting point guard D'Angelo Russell appears likely to be traded before the deadline and the Spurs should be interested in acquiring him. Russell is known for his shooting ability but he is also a skilled passer who can operate in the pick and roll and also find cutters for easy baskets. The Spurs don't have a guard that can do all of those things and adding Russell would give them a major upgrade at starting point guard.
Thus far, San Antonio has tried Jeremy Sohan at point guard as well as Malaki Branham, though neither have experience playing the position. That has resulted in San Antonio struggling to generate offense consistently and they are often outscored in the first quarter and torched in the third quarter as a result.
Russell would give them a steady presence at point guard who can effectively score 15 points a game while also setting up teammates such as Wembanyama for easy baskets. On a team that ranks 28th in offensive efficiency, he'd get them back towards respectability on that end by helping to get their best player the ball in favorable matchups.
While the Lakers are likely saving his salary for a deal involving a star, were they to strike out, the Spurs could offer up shooters such as McDermott, Cedi Osman, second round picks and recent first-round pick Blake Wesley to try and acquire him.
