Brown is a big, shut-down defenseman with little offensive upside. He contributes to the team by punishing opponents and using his strength to deny attacking forwards any comfortable spot to set up opportunities.
Brown is a project player who will spend another season in the OHL. His future success will likely be determined by his ability to develop into a pure, stay-at-home defenseman who can line up with the opponents toughest players.
