Caught my eye in the playoff series vs. Ottawa. Konecny drilled him into the boards early in a shift. Gets back up, continues to play, and then as Konecny tries to rush the puck up the ice he gets absolutely demolished by Dunn at the blueline same shift.
He may not be big, but he's got great skating abilities and a good sense of balance, making him a robust hitter at the junior level. Defensively he'll never be a shutdown guy, but it's effective and should at least be able to hold its own at the NHL level.
Honestly, his biggest weakness is that he gets too cute in the offensive zone sometimes. Little slow backhand saucers from one end of the blueline to the next, extra little dangles entering the zone....I swear every pass he made was off the ice. It's a testament to his skills that he makes it work, but if he simplified his game (to a certain extent, I still would want him to keep his flair for specific moments) he'd be absolutely dominant in the OHL.
As it is, I don't expect anything less than 65+ points from him this season. He'll be the clearcut number 1 defender for a contending team.
