Karlson was already robbed a third Norris trophy.Well, there's a decent chance he gets a third Norris this year. That pretty much guarantees a HHoF induction of it isn't already guaranteed regardless of what he does going forward.
If he keeps up his pace this year, he'll be one of only a handful of Dmen to hit 100 pts, and alone with Orr as the only ones to do it on a team with no other 100pts player (Esposito had 99, Meier is on pace for 77). I could be wrong, but I think he'd also be the only Dman aside from Orr to lead the league in ES pts too.
In terms of personal accomplishments, he's right up there with some greats. If he adds some team success all bets are off (hard not to wonder what his legacy would already look like had we beat the Pens)
