Can We See It From Ben Simmons in a Postseason Setting?

The question is still, can we see it from Ben Simmons in a postseason setting? It's been awesome to see him doing some of the things that we thought he could do in Brooklyn. But also in the month of December, in 120 minutes, he has not made a free throw in four attempts. And I feel like something like that is going to be an issue in a playoffs setting.
