13/40 points Kap played a direct part in. 7 before Feb 7th and 6 after. I'm willing to bet that a much larger portion of Eriksson Ek's and Boldy's points have Kaprizov as a direct contributor.
I think this shows that Johansson/Zuccarello are terrible options for Rossi. Hartman with Rossi yields some pretty nice underlying numbers. Same with Foligno.
