New Jersey Devils center Jesper Boqvist (90): (Eric Hartline-USA TODAY Sports) The New Jersey Devils learned a lot about the roster this past season. A lot of it was good. Yegor Sharangovich became a breakout star after a successful stint in the KHL. Janne Kuokkanen showed he was exactly what the Devils hoped when they traded Sami Vatanen to the Carolina Hurricanes. Jack Hughes pushed himself to a superstar trajectory. These are all great progressions for this young roster. One player who did not progress positively is Swedish winger Jesper Boqvist.
