"We are excited to add John to our coaching staff," said Nill. "He has a wealth of experience, both as a head coach and assistant, which Jim Montgomery will be able to tap into. Throughout his career as a coach, he has had both standout offensive and defensive teams, showing the ability to maximize the strengths of whatever roster he is working with."

The native of Campbellton, New Brunswick was originally drafted by Philadelphia in the third round (47th overall) of the 1984 NHL Draft and played parts of five seasons with Philadelphia and Hartford, totaling 10 points (0-10=10) and 48 penalty minutes in 53 NHL regular season games. In 834 career AHL games Stevens, a defenseman, had 188 points (21-167=188), 1,397 penalty minutes and won three Calder Cups: 1988 with Hershey, 1991 with Springfield (team captain) and 1998 with the Phantoms (team captain).

"I've always had a great respect for the way that John has approached the game," said Montgomery. "We were able to win a Calder Cup together in Philadelphia, and he is the best captain and leader that I ever played with. His knowledge of and his experience in this game will make us a better staff and we're excited he is on board."

He and his wife Stacy have two sons, John and Nolan.
