Chris Tierney is an intelligent hockey player; and a born winner. With an active stick and good skating, his defensive play predominately stands out; especially on the penalty kill. He plays this role for a very deep London team. Anywhere else, he might be known as a high-end playmaker given his skill set.
The excellent two-way centerman features solid puck skills, competitiveness, and hockey sense that when combined with his defensive reliability make him incredibly valuable. He has very good vision, and a knack for scoring big goals for his team. The way he integrates his team first style of play and is so heavily relied upon by his coach is reminiscent of a young Ryan Callahan without the vocal leadership qualities. Those are huge skates to fill, and Tierney has much to work on including improving his shot, but the potential is there for an NHL caliber difference maker.
Tierney will rejoin the Memorial Cup hosting London Knights for his third season in the OHL. Depending on what happens to some of the teams veterans who look to be NHL bound, Tierney could find himself in a bigger offensive role.
