I would have heavily vouched for Erne to make the team, but that was before the injury. He's going to crush the QMJHL with his strength advantage, I hope they are working with him to focus on the weak areas of his game.
It'll probably be his offense that benefits most. More than ever, he'll be "the guy" in Quebec. In all likelihood, he'll get a season in the A too, and join the Lightning as a 21 year-old Calder darkhorse.
