Karlsson

Ottawa has reached an unofficial contract with them, and even taking on Ryan's they'd want a lot more , start with Schmaltz and add a few more top prospects. It's also not a good idea for teams regularly near the cap limit to take on a bad, long term contract.
Shaw has played in 68 and 51 games the last two seasons. He was always a max effort, try hard, played more physical than his size type of player. So, in addition to being an overpaid bottom 6 forward, the last two seasons could be a trend. Imo, trading Anisimov for Shaw would be so terrible of a trade for the Blackhawks, it'd give Bergevin an extra two years as GM.
