The Boston Celtics have signed Lonnie Walker IV to an Exhibit 10 contract, allowing the team flexibility with their 15th roster spot as they prepare for the upcoming season. Despite averaging 9.7 points per game and shooting 38.4% from three-point range last season with the Brooklyn Nets, there is speculation that Walker could be waived before the regular season begins, as the Celtics may opt to keep the roster spot open for strategic maneuvers. Insiders suggest that Walker's offensive skills make him a valuable addition, but his defensive shortcomings could hinder his chances of remaining on the team. The signing presents an opportunity for Walker to showcase his potential in training camp and possibly join the Celtics' title defense. Additionally, Walker's postseason experience with the Los Angeles Lakers adds to the intrigue of his acquisition, though his future with the team remains uncertain.
