McCoshen has the type of size that NHL teams covet in a defender but doesn't always put that size to good use. He has some offensive ability, including an above-average snapshot, that would be useful on any NHL power-play. McCoshen uses his long reach well and is generally sound in his own end but could stand to be a bit more physical with opposing forwards.
McCoshen skated for Boston College in 2015-16, providing both toughness and a big shot from the point for the Eagles in his junior season. With the Panthers trading Erik Gubranson to Vancouver there is speculation that McCoshen might sign with the Panthers and compete for a roster spot in training camp. He could also return to BC for his senior season, becoming an unrestricted free agent in the summer of 2017 if he does not sign with Florida. He plays a similar style to Gudbranson with the size and demeanor of a punishing defender.
