Kubalk and Tarasenko on the same line is pointless.
The line-up didn't include trades but was meant to show depth chart, which is very much a playoffs bound looking team with improvement in all areas of the line-up even if we lose a player to accommodate Pinto. Perhaps I would add that losing Brannstrom is riskier as the other D options from Belleville are waiver picks, Kleven is not yet ready.
I think Kubalik would produce with Norris and/or Pinto as a finisher. But trading Kubalik makes the most sense as he doesn't have a term and is the juicer sell than Joseph's 3 more years at $2.9x M.
