The first part of the video deals mostly with the Kevin Love controversy. The question about shot election comes at the 8:56 mark. If you're more of a reader, here's Isaiah's response:
I mean, if they’re worried about my shot selection, they must not’ve seen me play the last few years. Like, that’s all I can say about that. If somebody’s worried about that, what did you trade me here for? To not shoot? To not find my rhythm? To not be Isaiah Thomas? I can’t be anybody else. So, whoever’s saying that, I mean, I don’t know what I’m here for if I’m not here to score the ball and make plays.
