Erik Karlsson became the first blueliner to reach the 30 assist mark on Friday. Only 29 defensemen in total ended up with 30 assists last season, but Karlsson didn't even need half a season to achieve that feat. Karlsson is also leading all defenseman with 35 points in 38 games. If Karlsson can maintain this pace, he'll become just the fourth blueliner to reach the 70-point mark in a single season since the lockout. The other three are Mike Green, Nicklas Lidstrom, and Sergei Zubov.
