When Predators forward prospect Filip Forsberg discusses his recent high school graduation back home in Sweden, he does so in his typical understated nature. “It was great, of course,” he said. “It was a big moment for me, and I’m proud of it.” While that was clearly an important day in the 18-year-old Forsberg’s life, it probably will pale in comparison to what he has coming up this year — potentially a full NHL season playing important minutes. The Predators indicated that Forsberg likely would be on the roster for the season opener in October. The player who still very much looks like a high schooler hopes to be ready. His priorities are to “get stronger and to play at a higher level and get up to speed a little bit. Those are two things I really focus on.” Forsberg is a little different from most other prospects in Predators development camp at Centennial Sportsplex this week. Acquired by Nashville in a trade with the Washington Capitals on April 3, he played in five games near the end of last season and scored a goal. The small taste of the NHL gives him some things most other prospects lack: a better overall sense of the team, its attitude and what the coaches want from him in the upcoming season — if he does indeed stick on the NHL roster. Said coach Barry Trotz: “When Filip came in, I tried to prepare him that we were going to play him and you end up against some people who are higher quality than he has been used to.” The Predators believe that with the veteran forwards they acquired when free agency opened last week — Matt Hendricks, Viktor Stalberg, Eric Nystrom — Forsberg should feel even more confident jumping into the lineup. “I like the type of people we brought in,” Trotz said. “Guys like Hendricks and Nystrom really fill in that grit factor, and that backbone factor, so some of the young guys we have in our lineup can feel comfortable out there.”
