That short taste of the NHL helped Sprong realize a few of the holes in his game, mostly on the defensive end. During the past two years, he's worked to become more reliable in his own end.
"I remember when I was in the NHL, watching a lot of games here at home and just seeing what guys are doing in the D-zone and how I could put that in my game," Sprong said. "I know what I have to do on that side of the puck. My skill level will take over on the other side."
Being sent down then made him hungry for more.
"It was a dream come true to make the team at 18 years old," Sprong said. "Playing 18 games and scoring twice, it's something you'll never forget. I had a taste of it and I got sent down."
That attitude fit in well with Sprong's new role as a leader during Pittsburgh's prospect development camp in late June. Despite younger than many of the other prospects, Sprong said he accepted and welcomed that challenge.
Director of player development Mark Recchi was glad to see Sprong step in as a veteran.
"This is great for him," Recchi said. "He can help them, he can help the guys. That's what we look for. I did tell Daniel that, that you're a leader here now and we expect you to look after these guys. So it's good."
Sprong underwent successful shoulder surgery in June 2016 that kept him out of development camp last year. He's fully recovered and appreciates how it taught him to handle adversity.
"It was a frustrating time," Sprong said. "You want to play and you want to see if you can make the NHL, but that's something I had to go through. I think I learned a lot and matured a lot during that time."
