I'm not entirely sure if kane is able to run a one man show nowadays by himself (aka/3rd and 4th liners). He isn't in his prime any longer, and doesn't have the depth on his team to put him in situations that could take advantage of other teams. (playing against weak competition)
We won Cups by having amazing depth, not loading up the 1st line and saddling Kane with garbage. Kane palyed with whom back in the day? Sharp/Handzus, Richards/Versteeg, Toews/Buff..where exactly is the garbage outside of Handzus? He always had a really good winger or centre with him.
Kane has scored 5 pts at 5 on 5 ES this year, and Schmaltz has been in on 4 of those. He may actually need a Schmaltz this year, 5 on 5 ES. If you put Anisimov with him, not only is our 3rd line now a 4th line, it weakens Kanes line by quite a bit.
