The Blackhawks had the option to send Dach back to his junior team, the WHL's Saskatoon Blades, as long as Dach played nine or fewer games this season, in turn delaying the start of his entry-level contract for a year. After six games, Chicago has seen enough to forego their remaining three-game trial run.
The 18-year-old has said from almost the moment he was drafted that he wanted to prove he belonged in the NHL this season.
"It's thrilling and exciting for me," Dach said after it became official. "It's something I've dreamed of my whole life. I came into camp wanting to make this team and to finally get that recognition from Jeremy and the management group is awesome and I'm thrilled to be here."
