It sounds like Jenner is day to day, but i think they are playing it safe right now. I wouldn't expect him back for the first few games.
Anyway, I think the lineups the last two games show us what we are looking at for opening night. It is hard to know who sits of Hannikainen, Motte, and Dalpe - but just a wild guess, I think Hannikainen is in and Dalpe has the momentum. I would imagine that battle will change game to game. Decisions will get tough once Anderson and Jenner come back. I believe Motte is the only one that can be easily sent down and is on a two way deal. And I think Schroeder will definitely make a push depending when he gets healthy. A few variables will factor in over the next few weeks, but I think this is how we are starting:
Panarin - Wennberg - Atkinson
Dubois - Foligno - Bjorkstrand
Calvert - Dubinsky - Milano
Hannikainen - Sedlak - Dalpe
(Motte)
IR - Jenner, Schroeder
x - Anderson
Werenski - Jones
Johnson - Savard
Murray - Carlsson
(Harrington, Nutivaara)
