The writing with Stalberg is on the wall.
Once Dzingel/Pageau are dealt with and Turris is extended, we'll have at least 12 forwards on 1 way deals this season and 13 next season when McCormick's 1 way kicks in.
Now a trade is possible, but 13 forwards on 1 way deals is a log jam. I would guess we prioritized getting a C, and with Pyatt willing to sign for relatively cheap, Pyatt and Thompson pushed Stalberg and Wingels out.
If there is a deal on the table for Stalberg, my guess is it is something to the effect of "look this is what we can do, if you want it, let us know". It's probably a low ball 1 year 750k type deal. We're at 65M in salary right now with Dzingel, Pageau, and a 23rd forward having to be paid, o I can't see us dropping 1.5M on Stalberg at this point when we already have 12 forwards on 1 way deals. I especially can't see us giving another bottom 6 player 2 years unless there's a big trade we are ready to pull the trigger on that'll move some bodies out.
