What we expected is what we got. Very mature young individual that's focused. He is on the right track. He's not only a great hockey individual, but he's a good person off the ice. He seemed to take a leadership role with this group right off the hop and ran away with it, and was vocal, was respectful, was everything it takes to be a Panther. His future looks bright.
