Karlsson has already stated that he would love to play in the postseason, and he and the Sharks have reached an agreement on it. Now that San Jose is far from a playoff berth, it appears like Karlsson is ready to hit the trade market.

This will NOT be doable for many playoff teams, this is nearly the same as the PK Subban situation dating back to this summer where not many takers may be interested in their abilities, for the hefty price.
