The Boston Celtics have been in a slump for nearly a month now, and Kristaps Porzingis isn't pleased with the team's effort amidst their struggles.

The typically optimistic Kristaps Porzingis struck a different tone Wednesday, calling out the Celtics for lacking "spirit" and "personality" in their loss at Toronto.

Porzingis was one of the few offensive bright spots in the loss for Boston, scoring 18 points on 7-of-11 shooting, including 4-of-5 from 3-point range. Boston shot just 39.6 percent as a team though with All-Stars Jayson Tatum and Jaylen Brown combining for 26 points on 32 percent shooting.
