Personally I feel you are being optimistic
Bolland on Chicago has gotten PP time which has given him some more goals. But with Bozak + Kadri here in Toronto I don't see Bolland getting much PP time, if any so I don't think we can count on him getting the 15-20 goals that he used to, but more likely around 10. And then Kulemin in the past has largely benefited from others creating the offense with him finishing (Kadri/Grabo/MacArthur). If his linemates are Bolland and McClemant, I don't see much offense being created by them not allowing Kulemin to finish it off as often. I'm feeling about 10 goals for everyone on that line, I don't have that high of hopes.
