Kemba Walker said his lack of aggression was "unacceptable" after taking only nine shots in the Boston Celtics' 100-93 loss to the Toronto Raptors in game 4.

The series is now even at two.

"I got to be more aggressive. I wasn't aggressive enough. That's unacceptable on my behalf, to be honest. There's no way I can just be taking nine shots. That's unacceptable," said Walker.

Walker finished the game with 15 points and 8 assists, while also going 1-for-6 from three.

Jaylen Brown, who shot 4-of-18 from the field, echoed Walker's struggles. 

"I just missed some open shots. I'm a good shooter. I've just got to make them. It's make-or-break time, 2-2. The series is tied up. We didn't play that well. I didn't play that well. We got to bounce back and be ready to fight. That's what it comes down to: fight. We have to be ready to fight for our lives next game and keep playing good basketball."
