He’ll help fill the void with Klay Thompson out
There’s no need for Williams to be on this team if Klay Thompson is still active. However, Thompson tore his Achilles while preparing for the season. After a torn ACL to end the 2019 season, Thompson’s new injury leaves a void.
While Curry will still be the unanimous leader on this franchise, Thompson served a purpose. He was an elite three-point shooter, one of the best in NBA history. He was also a top-tier defender that played a large role in leading the team on that end of the court.
Thompson’s injury will create a void, one not easily filled.
Williams can’t even fill that void completely, but on the offensive end, he can at least help. An explosive option off the bench, Williams would bring something Golden State hasn’t had much of, bench scoring.
While it’s not necessary, Williams’ scoring, primarily from deep, would increase the potency of Golden State’s offense, something that’s never necessarily a bad thing.
