I mean, I agree with him to an extent. While it is good that he can somewhat space the floor and knock down the occasional three, they should be playing more inside/out with him, because given his size, athleticism, length, and skill, Embiid is nearly unguardabke when down on the block. He shouldn’t be floating around the three point line so much.
That said, that’s primarily due to the makeup of their team. Having a complete non-shooter in Simmons and an average shooter in Butler, both of whom thrive by having open lanes and the spacing to penetrate and get to the bucket and/or line, means it best serves the team to play Embiid out on the perimeter quite a bit more to give them that spacing.
That’s just how it has to be when you have that specific talent that isn’t that complementary.
