Spurs: The 4 Best free agents and trade targets ahead of free agent frenzy

Offseason Target #2: Grant Williams

If the Spurs want to get imaginative with their cap space this summer, they could take a run at Boston Celtics power forward Grant Williams. Williams is expected to cash in after developing into a key contributor for the Celtics. While he will be a restricted free agent, Boston probably won't match a strong offer by another team due to the new collective bargaining agreement. That could open the door for the Spurs to sign Williams to a deal worth $72 million over four years.

Despite only being 6'7, Williams has developed into a solid power forward thanks to his versatility on both ends of the floor. On offense, he can knock down open threes and attack closeouts. On defense, he was often tasked with guarding bigger wings such as Kevin Durant and Giannis Antetokounmpo but held his own thanks to his sturdy frame and quick hands.

At 24 years old, he definitely fits the Spurs' timeline, though adding Williams would likely force the team to adjust their frontcourt rotation. At the moment, Wembanyama and Zach Collins are projected to start at power forward and center next season, while Jeremy Sochan will log significant minutes playing power forward next to both players.

However, if the Spurs were to sign Williams, that would force Wembanyama to possibly start at center next to Sochan, with Collins and Williams backing them up. That would make for a terrific big-man rotation, but there probably wouldn't be enough minutes to go around unless the Spurs moved Collins. Even then, signing Williams would be a smart use of their cap space, and San Antonio would have until the trade deadline to see how it works before having to make a decision.
