Reinhart has great size, budding talent, and good bloodlines. He has good hockey sense to go along with his size and ability. While he doesn't excel in any one area of the game, he doesn't have many weaknesses, either. Reinhart can work on his skating, and he could still make better use of his size.
Reinhart made the Islanders opening night roster in 2014-15, appearing in three games before being sent to AHL affiliate Bridgeport for his first pro season. Expected to be a staple on the New York blueline for years to come, he will need some time to adapt to the speed and strength at the pro level and refine his game. Long-term he is projected to be a top two pairing defender that is effective on both ends of the ice.
