Dermott is a 27 year old left shot defenceman that was drafted in the second round by the Toronto Maple Leafs. He's a smooth skating defender, able to make a play, and has positive analytics by all accounts. He's played 329 career games in his career and made a few playoff appearances, but struggled last season with the Arizona Coyotes. The Oilers can likely get a lot more out of him than Arizona.
Dermott's training camp has impressed many in Edmonton, and he's surely earned another opportunity in the NHL. Hopefully the Oilers will be able to keep him for depth, because otherwise another team will likely come to sign him. The puck drops on the Oilers regular season this Wednesday!
