The hardest part of presenting Karlsson's statistical achievements is figuring out where to start.
The Senators captain has always been an outstanding two-way defenceman, but this season he took it to another level. A third Norris Trophy may be waiting around the corner after this year's display of brilliance in the offensive end and command in the D zone.
To start off, let's take a look at what the 2016-17 campaign meant for the 26-year-old. Finishing with a total of 71 points in 77 games played, he added yet another historical offensive season to his soon-to-be Hall of Fame worthy resume.
Since 2010, there have been 15 60-point seasons by a defenceman; Karlsson now has five of them. In that same time frame, there have been seven 70-point seasons by a defenceman: Karlsson now has four of them.
Though he was unable to reach his career high of 82 points, Karlsson created a new career high in a similar category. An argument for the Swedish sensation to win the Hart Trophy as league MVP has always been how much of an influence his play has on the Senators' overall offence. When in the lineup this season, Karlsson was in on 36.2% of the team's goals, surpassing his previous career high of 35.6% last year.
Karlsson is also setting career highs on the other side of the puck. His 201 blocked shots this season have him second in the league and far above his previous career high of 175. Only ten players have surpassed 200 blocks in a season since 2010.
