"It has been an up and down season for Bernier. After an outstanding camp, the backstop found himself in London, England starting the season against the Stanley Cup-champion Anaheim Ducks. Bernier played well, but didn't get much defensive support. The Kings returned him to junior to avoid stunting his development. He earned a spot on Team Canada for the world juniors, then controversially lost the starting job. But Bernier is close to being NHL-ready. He'll get another chance to start next season."
