Scottie barnes has been fuckin amazing to start the year. He’s had good numbers, but even his numbers don’t do him justice now that he demands respect out to the 3 point line and his handles are starting to improve, it’s opened up his offense so much. And defensively, idk if it’s a scheme thing that was holding him back last year or poor health, but he looks like a damn monster on that end.
