Deslauriers and Seeler are pretty much it, and I won't be surprised if Deslauriers sits a bit if some young players step up.
Farabee - Couts - TK
Tippett - Frost - Atkinson
Laughton - Cates - Foerster
Deslauriers - Poehling - Hathaway
Lycksell, Allison, Laczynski, Desnoyers, Brink (3 start the season in LHV)
York - Walker
Sanheim - Risto
Seeler/Staal - Zamula/Attard
(Grans, Ginning, Samson at LHV)
Hart/Ersson
The key issues are health, Couts and Atkinson of course, but Walker is now 2 years form an ACL injury, was a solid 3RHD last season and if he raises his game and is a passable top 4 D-man, could be major trade bait at the TDL if the Flyers are out of the PO race.
It's actually not an awful lineup if Couts and Atkinson rebound, with Gauthier, Andrae, Bonk, Kaplan, and Michkov already in the wings.
To be a SC contender they need to be a consistent 100 point team. The offense just has to be top ten or so if they improve the defense and the goalie pipeline keeps delivering, Solid but not great offense is enough with good defense and top goalie play. Which means the focus the next couple years, given the forwards and goalies in the pipeline, should be to upgrade the defense.
