His ceiling is multiple Norris'. I see him reaching it any time now.
One of the things that hurts his perception nationally is that he doesn't get #1PP time. That's not because he isn't good on the PP, but rather because he's our #1PK guy as well as our shutdown guy, and with other decent options as the PP guy, he doesn't get a ton of time there. Look at the best offensive Dmen in the league, and you'll see they probably get a full half of their points (if not more) on the PP, which Hedman isn't getting. He still produces ES very well, he's amazing with the puck, he's a rock solid defender, and he's severely underrated.
Which I'm fine with. I can think of maybe 5 Dmen in the league I'd rather have, and a couple of those are borderline. He's a beast.
