From The Hockey Writers blog,
Potential breakout rookies:
Columbus Blue Jackets
Best Bet: Alexander Wennberg, F — Not sure if there’s room for any new kids in Columbus’s forward ranks, but Wennberg could force his way onto the roster. Marko Dano might also be in the mix, but neither would be hurt by some AHL seasoning as they adjust to the North American game.
Honourable Mention: Jerry D’Amigo, F — He’s getting a change of scenery from Toronto, but ice time won’t come any easier in Columbus as he’ll be in a battle to crack the Blue Jackets as a fourth-liner or extra forward.
Long Shot: Simon Hjalmarsson, F — He’ll also be in that battle, having been signed as a free agent this summer after putting up more than a point-per-game in the Swedish league in 2013-14. Jarmo Kekalainen is quite the talent hawk, so Hjalmarsson could be a pleasant surprise in 2014-15.
