Completely rational. But I think it's important to know it's not like he has presented with all this opportunity to break out. We weren't in a position to let Exum get shots and create, whether that meant succeeding or failing. A lot of possessions he played off ball and literally never crossed the 3 point line.
I'm pretty sure that's on Exum. Nobody told him to hide in the corner. And he has gotten plenty of opportunities.
