Hey remember when Kevin Bieksa was going to be traded to the Sharks? It almost happened, but the Sharks wouldn't give up a second rounder in the 2015 NHL Draft.
So the Vancouver Canucks did the proper thing, which was to spite them by trading Bieksa for a 2016 second-round pick and sending him to the Sharks' rivals. Hence, Bieksa is now a defenseman for the Anaheim Ducks.
From the Ducks:
The Anaheim Ducks announced today that the National Hockey League (NHL) club has acquired defenseman Kevin Bieksa from the Vancouver Canucks in exchange for a second-round selection in the 2016 NHL Draft.
