The undrafted rearguard suited up for 53 games with the AHL's Stockton Heat last season (since relocated and rebanded to the Calgary Wranglers), notching five goals and 36 points. He added a goal and four points in seven postseason tilts.

"It's really exciting," he said. "I mean, most excited I've been coming here to camp.
"Seeing everybody and we have some new faces as well and knowing it's a big year for myself. There's definitely pressure that comes with it but that's just part of the game, you gotta kind of embrace it and go out there and play my game.

"I pride myself on being a two-way defenceman, taking care of my own end first and foremost, and obviously, we want to win hockey games in the preseason and ultimately my goal is to make a team so that's what I'm looking to do," he said. "And prove to everybody I can play at this level consistently."
Mackey had a great opportunity in Saturday's intersquad scrimmage to skate on a pairing with highly-touted offseason acquisition MacKenzie Weegar and should start alongside him tonight.
