We have more actual NHL players now, but I'm not sure "the core" is a nucleus for a successful team.
I'd disagree, but only if Meruelo comes through and will spend money. I'm going to leave the 'X' where I think we need to add.
Keller-X-Schmaltz
I still see a 70-80 point player in Keller with the right linemates. Tarasenko cieling. Schmatlz isn't far off but is a more complementry player.
Gally-Dvo-X
Gally depends on re-signing him but is a gifted goalscored and a 1st line tweener. Right linemates will let him excel, as long as we can re-sign him, he is the type of player you don't let go. A top 6 player who flashes top line skill. Dvo is still a mystery but is a solid 3C already. If he becomes a faster Stepan in his prime clone there doesn't need to be anything else said. Really need another top 6 here.
Crouse-Hayton-Hino
Crouse still has top 6 upside. Has the ability to be the new "desired" style of player in the NHL where he is a speedy, dumpster truck who can hit and score. It's a rare talent, but may top off at 30 points instead of 50+. Hino is a TyJo/Gourde clone with the right linemates and lineup fits. Hayton works here at the VERY least.
X-X-Garland
I'm just trying to include the "core" and Granber won't be part of that, not Ritchie. Garland could be. He may also be able to hit the top 6, or be cut entirely either way his development will be interesting and unexpected.
What I'm drunkenly getting at is you fill the right players into those X's and the forward lineup starts to look tough to play against. We have too much speedy skill players, but not enough Crouses. That can be supplemented in the X spots. I think it's a good core because of depth rather than top end skill. Blues not Tampa.
Without an owner with money those X's are more Grabners and Ritchie's, with one those are Duchene's and Zucker's.
