Problem is, they don't have enough talent on the wings overall to try to run 3 balanced lines. So, one of Strome or Dvorak will get shafted. They have 4 pretty good wingers or better in Keller, Domi, Perlini and Duclair. Fisher is also pretty good, but also young. Maybe the try to run a top 9, but Strome or Dvorak with other young guys, but a coach will always have issues depedning too heavily on that, and the only winger has proven to be somewhat consistent at the NHL level is Domi. Duclair has always been inconsistent, while Keller, Perlini and Fisher haven't really played many NHL games. I'd try something like this, but it could lead to problems.
Perlini-Stepan-Fisher
Domi-Strome-Duclair
Keller-Dvorak-Rieder
But, that leads to a minutes cut of guys like Domi, Stepan and Keller, but it gives all their young players a chance to play with actual talent, but puts a heavy emphasis on each of Domi, Stepan and Keller to somewhat carry their lines.
