6 'Spurs culture' free agents that might suddenly want to sign with San Antonio

No. 4: Grant Williams, Boston Celtics

Grant Williams is like an onion. Or a birthday cake. Or an ogre. That is, he has many layers to him.

Grant Williams' mother works for NASA. His dad worked for Michael Jackson. Grant plays at least four instruments proficiently. He was in musicals singing and dancing in high school. He was onetime nationally ranked in chess. He loves board games, Fantasy novels and mathematics. He's a true NBA Renaissance Man, and there's perhaps no one who fits better on a Gregg Popovich team than a Renaissance Man.

Williams is certainly no slouch on the basketball court, either. He has emerged over the past couple of years as a true 3-and-D forward, shooting 39.5 percent from 3-point range this season while providing excellent defense both on the perimeter and defending burly centers.

He would be an excellent fit with Victor Wembanyama, spacing the court on offense and able to take on the larger centers defensively who would knock around the relatively light Wembanyama. Whether he started at the 4 or came off the bench behind Wembanyama and Keldon Johnson, Williams would unlock a lot of lineup versatility for the Spurs. He also brings experience, having made it to one NBA Finals and possibly a second this year, and that experience is valuable on a young team like the Spurs.

The question is how available Grant Williams is this summer. He is a restricted free agent, so the Boston Celtics will have match rights on any contract he signs. Williams has been somewhat marginalized in the rotation in the playoffs, perhaps signaling that the Celtics don't have the stomach for a solid offer from another team.
