Miss not having capgeek to verify all of this, but we may not be as terribly far off, given the haul from the deadline.
On team next year: Domi and Duclair/Samuelsson will likely be up. 3 if we do get McDavid or Eichel
2 years from now: both Duclair and Samuelsson are up, decent chance with Perlini, decent chance with Dvorak, maybe Marner/Strome if we do not get 1/2
3 years from now, it is absolutely safe to say these players are getting regular time:
2015 1st round pick
Domi
Samuelsson
Duclair
Perlini
Dvorak
Assuming Boedker, Lessio, Rieder, and Gagner stay, that is 10 of the top 12. We still have a potential pipeline in the AHL of LaPlante, Dauphin, Karlsson, Macinnis, and Letunov, all of whom could be ready in 3-6 years/from now. That is not bad for the forwards, considering the only draft pick that I have mentioned is the 2015 1st.
Defense has players who are signed or cost controlled for a little while. We need to be smart about locking up Murphy, Stone, and at least 2 of Dahlbeck, Gormley, and Moore. Get OEL to extend as soon as we can. Other D are a little frightening down the road. Seems like both Mayo and Westlund have more upside than any others, so it would not hurt to monitor that in the draft.
Big picture - 3 years to wait on this will suck, but there have been weirder scenarios where certain players develop at a fast enough rate or the right FA comes along that fits this team like a glove before this 3 year window hits.
