Curcuruto is a two-way defender who does not excel at any part of the game but is dependable when he plays within his abilities. When Curcuruto tries to play beyond his abilities is when he gets himself into trouble. He has the skill to eventually become an effective lower-pairing defenseman, but his hockey sense is not yet well developed.
