In the NBA preseason, the Celtics defeated the Grizzlies 121-103. After the game, Green Army player Garza was interviewed.

Talking about how the results of the arduous training camp translated into the victory over the Grizzlies in the first game of the preseason, Garza said: "We must not only play a fast-paced game, but also maintain a high level of concentration and insight on the court. The key is not to be quick and fast, but to play smart and fight aggressively. I think we did a very good job in this regard throughout the game."

In this campaign, Garza scored 10 points, 10 rebounds and 1 block.
