I'd definitely like to see Dube get a shot at playing with the second line, but I don't see the current 3rd line lasting very long.. mangiapane should definitely be playing as he's one of the flames more skilled forwards. A 3rd line of Mangiapane Ryan Bennett would probably be ideal with lucid janko and frolik on the 4th.

Also, Brodie is always better on the right side so I could see him playing with Hannifin at some point because Andersson will most likely end up with Gio. And then a valimaki hamonic pair would be pretty solid as well.

Johnny_G13 covered most of the even strength stuff, I do want to also see Bennett get a top 6 chance as well. As for Special teams:
PP1 is fine. Lindholm and Monahan share the dot depending on what side its on but they choose now so Mony will probably get most draws.

PP2 can probably be adjusted a bit. At the blue line i would probably run Valimaki and Andersson. Then have Bennett, Backlund and 1 other player (currently Lucic to cause havoc in front of the net) upfront.

PK1 should 100% be Jankowski, Lindholm, Gio, and Hamonic.

PK2 should normally consist of Backlund, Ryan, Hanifin, and Stone. Other players that can play the PK as well are Frolik, Bennett Andersson, Rieder

It's a low chance that Peters splits up Hanifin and Hamonic.

Gio - Andersson
Hanifin - Hamonic
Valimaki - Brodie
