Trade targets I can think of now the dust has settled a bit:
Toffoli or Kempe - LA is crunched a bit and might prefer one over the other. They probably need to ditch some salary.
Bjugstad - Florida might want to sell high. Big body, RHS. I don't like buying high but Chayka doesn't get taken for rides.
Zucker - the Wild might prefer taking assets for him instead of paying him, freeing up a spot for a younger player
Miller or Tyjo - Tampa might want to ditch one for the right price even if they don't get Karlsson.
Burakovsky - no longer cheap or waiver exempt, the Capitals might want to trade him for something
Nyquist - after taking Zadina from us, they might also take another young player for this UFA to be.
K.Hayes - NYR in rebuild, might offer him up for something reasonable.
