Grant Williams is a restricted free agent this offseason after he and the Boston Celtics failed to reach an agreement for a contract extension last summer. Even though Williams has developed a reputation as one of the best young 3-and-D wings in the NBA, Boston’s cap situation is precarious after it acquired Kristaps Porzingis in a three-team deal.
As such, Williams could potentially find himself fielding contract offers that Boston will not be willing to match. Should Williams accept a deal from elsewhere, the Celtics would be losing a homegrown talent, with nothing coming back in return. Such is the risk of free agency.
