1) I doubt Chicago would add to that, if those reports about the offer they turned down is correct.
2) It would absolutely be the opposite of how winning teams during the salary cap era have been built.
Those teams had multiple top five/ten picks and built with those players to become Stanley Cup champs.
Just look at Tampa, Pittsburgh, Chicago, L.A. or Colorado built their teams.
None of them took the quick fix route and traded high picks(besides Drouin for Sergachev, which was later on, after Drouin was in the league for a couple of years) in order to get right now guys.
And as nice as DeBrincat only being 24 is, that #4 pick will have about seven years of control, while DeBrincat only has three more and is already at a pretty big cap hit that will increase one year from today.
