Chicago has 3 guys who will most likely get new deals at the end of the year Saad, Kruger, and Oduya. The only contract up at the end of the year that is more then a 3 year deal is Vermette, and he's not getting a deal like he did from the Coyotes from the Blackhawks. Darling is signed through 2017, so they will not be looking for another backup.
The rest of the core players are up the next two years. Seabrook, Versteeg, and Shaw in 2016 and Sharp and Bickell in 2017. Hjalmarsson's contract ends in 2019.
