4 - The number of defensemen in the league who have more primary assists at even strength than John Carlson's 5. Those defensemen? Tyson Barrie, Paul Martin, Hampus Lindholm, and Aaron Ekblad, all of whom have notched 6 main helpers at 5s. Honorary mention for Cody Franson in Toronto who also has 5.
Not bad stuff from Carly, whose assists have helped him notch points on 57.9% of goals that are scored by his team when he's on the ice— good enough for fourth in the League among defensemen, trumped only by Alex Pietrangelo, Jake Muzzin, and Aaron Ekblad.
