Celtics reportedly sign guard Caleb Grill to training camp contract

The Boston Celtics have reportedly bolstered their training camp squad by signing guard Caleb Grill to a contract, according to reports from HoopsHype. The move adds further competition to a roster that is currently navigating specific salary cap constraints, which are expected to influence the final structure of any new agreements.

Grill, a 6-foot-3 guard aged 26, brings a diverse background to the team. He played college basketball for UNLV, Iowa State, and most recently Missouri. His professional experience includes stints in the NBA G League with the Greensboro Swarm and the Windy City Bulls, where he demonstrated consistent scoring ability.

During his time in the G League, Grill averaged 10.1 points, 3.3 rebounds, and 1.0 assists per game. His shooting efficiency was notable, with a 38.5 percent success rate from beyond the arc, 71.4 percent from the free-throw line, and 43.9 percent from the field overall. These statistics provide a baseline for his potential contribution to the Celtics’ backcourt.

The signing places Grill in direct competition for an open regular or two-way roster spot. He will vie for this position alongside Milos Uzan, a standout from the Las Vegas Summer League, and Devin Carter, a former lottery pick by the Sacramento Kings. Given the Celtics’ current cap situation, analysts suggest that any secured spot would likely be a two-way deal rather than a standard NBA contract.

While the primary expectation is that Grill will use the training camp as a springboard to secure a position with the Maine Celtics or another league, the outcome remains uncertain. The competition is stiff, but Boston’s need for backcourt depth creates a pathway for Grill to earn a place on the main roster if he performs well.

The deal has not yet been officially confirmed by the Celtics, with the initial report originating from HoopsHype. As training camp progresses, Grill’s performance will be the determining factor in whether he remains in Boston or moves to a developmental affiliate.
