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 attended his first training camp with the Oilers in 2015-16 — making the team out of training camp before suffering an undisposed injury — and has shuttled between Edmonton and AHL affiliate Bakersfield in his second pro season. Returning to Edmonton where he won a Memorial Cup with the OilKings, Reinhart is expected to develop into the player envisioned when the Islanders took him with the fourth overall pick in the 2012 NHL Draft. Progress has been slow to this point though his skill set suggests he can be a top two pairing defender.
