Costello is a feverishly hard worker both on and off the ice. Goes into the corners and works hard on the forecheck. Can take hits and deal them out. Very persistent at both ends of the ice. Just a good two-way player who will do what is asked.
Costello is attending Notre Dame University. He was dealt by the Ottawa Senators to the Vancouver Canucks in exchange for Patrick Mullen in March of 2014.
