Celtics Notes: Boston Cuts Ties With Guard, Al Horford Latest, Breakout Player Predicted

In this story:
The Boston Celtics cut ties with a rookie guard as training camp is right around the corner. After recently being signed to an Exhibit 10 deal, he is expected to join Boston's G League affiliate, the Maine Celtics, according to a team insider.
In other news, veteran big man Al Horford has a troubling update to his free agency saga. He has been linked in recent weeks to a Western Conference contender as the deal gets closer to likely becoming official.
Finally, a team insider predicted one Celtic in particular is bound to have a breakout year. After averaging 19 points, 5.3 assists, and five rebounds across 10 games played without superstar Jayson Tatum last season, the case can certainly be made that a breakout campaign is in the works.
