That has not transpired, it's been pretty much a disaster season. Campbell has shown flashes of brilliance in his game, but overall it has not improved.
It's suggested by Eric Duhatschek of the Athletic, that Edmonton might try to move the beleaguered goaltender during the summer and that possibly San Jose could be a team that could look at him for their rebuilding phase.
A trade like this would take time, and a willingness to eat some money to make a trade work. The Oilers will need to do something to get out from under this contract as the goaltending upgrade has not occurred, and he doesn't seem to be improving.
