The Stars made two major changes after missing the Stanley Cup Playoffs for the second time in three years. Ken Hitchcock was hired as coach to replace Lindy Ruff, and Dallas acquired goaltender Ben Bishop from the Los Angeles Kings.
"We've got some of the key things done this offseason, and that started with our coaching staff and signing Ben Bishop," Nill said. "Now we just have to fill some holes in our lineup."
The Stars will focus on filling those holes after a draft when they made three picks in the top 39.
On Friday, the Stars selected defenseman Miro Heiskanen with the No. 3 pick, then traded up from No. 29 to No. 26 to take Boston University freshman goalie Jake Oettinger.
Heiskanen is the highest pick the Stars have had since they moved from Minnesota to Dallas in 1993.
"It's something I don't want to get used to doing, but it puts you in a nice position," Stars director of amateur scouting Joe McDonnell said of having the third pick in the draft. "We had him first on our list. Even if we were drafting first [overall] I think we would have picked him."
Selecting Oettinger, the top-rated North American goaltender in NHL Central Scouting's final ranking, was part of the long-term plan for the Stars. Dallas signed Bishop to a six-year contract soon after acquiring him from the Kings on May 9, so there's no pressure on Oettinger to play right away.
