NHL Central Scouting’s B.J. MacDonald:
“Seth is a big, rangy defenseman who has a nice command of his shifts. He has the ability to be a game-changer because he has good instincts and awareness. He’s an underrated passer, possesses solid one-on-one play and can skate the puck out of danger at any time. He’s already the complete package, but I get the feeling he still has another gear to go to.”
