Dickinson had a rough year, but statistically, he had a strong career up to the Canucks and with the issues around the team to start the season, it's extremely possible that he didn't really blend well to start the season.
My guess and prediction is, that he will bounce back this coming season as he had a strong finish the last 15...ish games.
Give him a start under Coach BB, and if he doesn't come around in camp, then waive / trade him.
