Cosman, who enters his first year in the high school ranks at Hingham in the MIAA, has already developed a reputation as a perimeter scorer. A good shooter from behind the arc, Cosman does a good job of keeping spaced, provides an early target with his hands, and makes sure to square up to the rim on his jumper. He gets his shot off quickly amd does a nice job of exploding into his jumper. He plays hard, competes on both ends of the floor, and shows some nice athleticism. He’s capable of putting the ball on the floor and scoring at the rim and does a nice job of moving without the ball. Defensively, he has quick hands and shows good anticipation for the next play. He has a chance to carve out an early role at Hingham and is a definite prospect to track over the coming years in the MIAA.

Cosman hurt his back midway through his game on Thursday night, but he was his team’s most effective player before that. He showed off an impressive three-point stroke and some really advanced slow-step moves at the rim – something you don’t normally see from kids his age. He gets his shot off with good quickness and rotation, which will certainly be something he leans on at the high school level. I wouldn’t be surprised if Cosman gets some varsity looks for Hingham High School this upcoming season.
