Delia won his NHL debut, a 6-2 victory against the Winnipeg Jets on March 29, 2018. However, the night belonged to Scott Foster, a 36-year-old Chicago accountant and emergency goalie, who made seven saves after Delia sustained a lower-body injury with 14 minutes remaining in the third period.
Former Merrimack College coach Mark Dennehy, who coached Delia from 2014-17, said, "that's so [Delia]. First start, first win, and he won't be remembered for it. It'll be a 36-year-old."
But Dennehy, now coach with Binghamton of the AHL, said Delia's potential was evident at Merrimack, where he was 21-24-10 (ties) with a 2.48 GAA and .912 save percentage.
"I had been a part of the staff that recruited [Los Angeles Kings goalie Jonathan] Quick to UMass," Dennehy said. "[Quick is] incredibly fast down low and really tough to beat. And [Delia] has a lot of those similar qualities. He reminded me a little of [Quick]. They're different people and I think Quick's a future Hall of Famer. I'm not saying that's what Collin will be, but he's already proven a lot of people wrong."
Rockford goaltending coach Peter Aubry said Delia has always had good mobility but has really improved in tracking the puck.
"Because he was such a great skater for such a long time, he was used to doing moves and getting to spots. But he was able to hone his precision on where the puck is," Aubry said. "He's making better decisions on where to start for a play and where to end up. He's just really playing hard, puck tracking, reading the play. He's detailed in his approaches."
Delia is just as detailed with personal interests. One hobby is leather crafting. He made a leather duffel bag while attending Blackhawks training camp in September and was working on a mid-century leather couch at his home in Rockford when the Blackhawks recalled him in December. It's become a bit of a side business by word of mouth. Delia doesn't have a website for it, but he does have a name: Portiere, Italian for goaltender.
He also gets much of his inspiration from people outside of hockey, be it chef Gordon Ramsay or fashion designer Tom Ford.
"If you want to be elite, you have to look at people who are elite in their fields. You can't just look at people in hockey," Delia said. "The level of detail and the degree of certainty these people have, doing this and that. I'm attracted to that mindset. They're at the upper echelon of what they do, and I feel I'm on the way, too."
Delia has already done well with the chance the Blackhawks have given him. Those around him expect he'll only get better.
"Can he be a No. 1? I'm not scared to say it, yeah, he can," Aubry said. "He does a great job staying in the moment, but we've talked about looking big picture. It's important to project further than where they currently are, and we should do that with him. I'm not prepared to cap it and like Jeremy said, am I surprised he's having success? No, not at all."
