Don't forget Boedker
Those were pre-season lines for training camp. My guess is that the forwards competing for open spots will be Tkachuk, White, Brown, Paul, Batherson, Formenton, Chlapik, Gagne, Tambellini and McCormick.
The forwards on 1 way contracts are Stone, Duchene, Boedker, Dzingel, Pageau, Smith, Ryan, Pyatt and Paajarvi. Gaborik is also on contract but I think he will be injured to start the year so his spot is open. If no other player gets traded, that would leave up to 4 forward spots available. I think the top candidates to take those spots are Tkachuk, White, Brown and Paul. Formenton, Batherson and Chlapik are in the second group for me and then the dark horses are Gagne and Tambellini. McCormick is there because of his contract.
The three top six forwards are Stone, Duchene and Dzingel, although Dzingel could get pushed to the bottom six. The rest are just bottom six forwards. That leaves 3 top six forward spots open and one 12/13 forward spot. Part of the min focus is finding linemates for Stone and Duchene. Stone needs a LW and C, and Duchene needs a LW and RW.
Stone and Brown seem like a good match so the key will be finding a LW for that line. Using prospects the options would be one of: Tkachuk, Formenton, Gagne, Tambellini or Paul.
Duchene needs a LW and RW so using prospects he could play with some combination of: Tkachuk, White, Formenton, Batherson, Gagne, Tambellini or Paul.
