Castillo is a threat to leave a positive impact on the game in a variety of ways. He is a capable perimeter shooter who can knock down shots from three while playing off the basketball, and his fluid shooting mechanics allow him to consistently look comfortable from the outside. Castillo also uses his strength to establish good positioning on the interior and convert high-percentage scoring opportunities. I like the body control he shows when attacking, allowing him to stay balanced and finish effectively around the basket. His ability to impact the game both inside and out makes him an intriguing all-around prospect.
