The signing locks McNabb up through the 2021-22 season. He becomes one of just two players that are signed beyond the 2019-20 season (Reilly Smith).
McPhee- "McNabb is a very good defensive defenseman. He's got a long stick, and is good with his stick. He's locked down some top opposing players for us and we hope he's here for the rest of his career."

Nice! I like Nabby. Not a guy who’ll get a lot of points, but, a good stand-up guy on the defensive end. Hard hitter, too!
