I disagree with your premise. I believe Hartmann (1yr NHL experience), Panarin (2yrs NHL experience), Panik (3 yrs NHL experience) have potential to get better and that will in fact make the team better.
The same for Kempny, Schmaltz, Forsling, Hino, Hayden, Kero, and Motte.
Take a look at Ottawa. Half their team makes less than $2mil. Without a lot of superstar players they are giving the Pens fits (and already between the Bruins and Rangers)
Pittsburgh won last year with a lot of good young role players.

+100. Half of this board complains that the Hawks are too old and expensive, and then turns around to suggest trading away young promising players for 35-year old retreads.
