According to NHL's Briand Hedger, the Blackhawks are more than kicking tire on a few impact forwards. The same name as we keep hearing day in and day out; James Van Riemsdyk ($4.250.000 cap hit) and Gabriel Landeskog ($5.571.429 cap hit).
How could they pull this off?
Well, if eveything remains the same, the Blackhawks could add a $5.300.000 cap hit player with 40 days left to the season (trade deadline), The only problem is both of these players are under contract for the 2017-2018 and that's when Panarin's new deal will kick in ($6.000.000 cap hit). So it will be hard for the 'Hawks to acquire one of these forwards without giving a key piece of their core.
The Avalanches and the Maple Leafs said they were in for a top-4 defenceman, could the Blackhawks be willing to sacrifice Niklas Hjalmarsson or Brent Seabrook? Another option would be to trade one of : Marian Hossa, Marcus Kruger or Artem Anisimov and a blueline prospect like Ville Pokka or Gustav Forsling. That goes without saying, but the Hawks first round pick is well into play if that means adding someone like Van Riemsdyk or Landeskog.
An even more creative option for the Blackhawks: Trade for Landeskog or Van Riemsdyk and use him as a location before trading him right before the draft but that's an even more complex scenario.
