Has Patrick Roy's arrival and coaching systems influenced the kind of players that would thrive? Your team usually plays slow, defensive, physical games which would be buffered by Sorokin in the back, while Dobson/ Barzal/ Horvat/ Palmieri would be the sources of quicker offense that I can see. Lee as Captain and Pelech/ Pulock as the top D pair should be capable as ever.
Perhaps as mentioned, Nelson and Palmieri may go for younger players? Also I know Martin and Clutterbuck are on your Identity Line but I wonder if it's time to move them for cheaper guys, and I don't understand your love for Engvall, he's slow and not really that offensive for a top-6 winger. If anything, I think it'd make sense for some wings on short contracts to get moved for wings with upside and two-way games, since Horvat - Nelson - Pageau would still be a strong center group. The core looks strong overall but (maybe along with moving on from Holmstrom/ Wahlstrom, or giving them 3rd line roles?) the top end could still use help.
