"The Blue Jackets tried to trade into the late first round to draft Oscar Dansk, then sat delighted when he made it to the second. Dansk, they believe, has the size, skills and agility to be an elite goaltender, but first must adjust to smaller North American rinks. The process is underway in the OHL, but it has not been without bumps. Not only has Dansk been inconsistent in his first season with Erie, he's also been sidelined since mid-January with a concussion. Dansk was Sweden's No. 3 goaltender at the world juniors, winning a silver medal, but not appearing in a game." (Aaron Portzline, The Hockey News Future Watch 2013, p. 31)

"Dansk has blossomed in his second year of major junior, ranking as one of the top OHL goaltenders and leading Erie to a major turnaround from 2012-13. It took him 30 starts to double his win total from a year ago. After serving as a third-stringer in 2013, Dansk started for Sweden and was named best goaltender at the world juniors. He's very agile and athletic, but there is work to be done on the technical aspects of his game and his "default" positioning." (Aaron Portzline, The Hockey News Future Watch 2014, p. 27)

Backing up Malcolm Subban at T-Mobile Arena in Las Vegas against visiting St. Louis, Subban left with an injury with 9:10 left in regulation and the Golden Knights leading, 2-1. Dansk allowed a goal to Alex Pietrangelo but was solid overall, stopping 10 of 11 shots in a 3-2 overtime win. "I was lucky because it was a TV timeout, so I got a little more time I got to move around a little bit, so that was good," said Dansk, who was called up from Chicago of the American Hockey League on Thursday in favor of Maxime Lagace. "I tried to move around as much as I could."
