I think they should either put Zacha or Palmieri next to Gusev-Hughes. I think Palms would be good for that line but if they intend to keep him with Nico/Hall I rather they put Zacha than Simmonds there.
I like the Boqvist-Zajac-Bratt idea too
I could see them giving Palms a look with Hughes and Goose. Especially if Bratt starts hot because they will want him on the ice more.
Hall Nico Bratt - We know this can work, not as well as Palms but still be good.
Goose Hughes Palmieri - Just remember just because we think it will work doesn’t mean it will see Grabner.
Boqvist Zajac Simmonds - That’s a good 3rd line nice balance
Wood Zacha Coleman- that’s a 4th line that could do some serious damage and is a match up nightmare for most teams not named Tampa.
During certain games Boqvist rest Hayden plays 4th RW and Coleman or Zacha moves up.
EDIT: Moral of the story is there are lots and lots of possible options for the lines. Things will be tried, injuries will force things together. But I think it’s pretty clear that when your 4th line is made of guys who can all be middle 6 guys if needed your in great shape.
