"It's been really great," the defenseman prospect said. "It's a really hot place, a lot hotter than Finland. I like it here."
Heiskanen, the No. 3 pick of the 2017 NHL Draft, had plenty of things to like about development camp, most notably signing his entry-level contract July 8.
"I am really excited," he said. "It's a big day for me."
The Stars have big plans for Heiskanen, who is their highest pick since Mike Modano was taken No. 1 in 1988 when they were the Minnesota North Stars.
"We're excited for Miro," Dallas general manager Jim Nill said. "He's a player our scouts have watched all year. He's what you're looking for in a prototype defenseman nowadays. He can skate, he moves the puck, he's a guy that's never under pressure. The game looks awful easy to him."
Heiskanen (6-foot, 170 pounds), who turns 18 on July 18, had 10 points (five goals, five assists) in 37 games with HIFK in Liiga, the top professional league in Finland. He also had 12 points (two goals, 10 assists) for Finland at the 2017 IIHF World Under-18 Championship, and was named the tournament's best defenseman.
The Stars' other prospects got a firsthand view of Heiskanen's skill set during the five-day camp at their practice facility. Jason Robertson, their 2017 second-round pick (No. 39), went head-to-head with Heiskanen during a puck-control drill Sunday and was impressed.
"He's a very skilled guy, not only on defense, but when I was on defense and how he handled the puck," Robertson said. "I was shocked at how good he handled the puck and how well he skated."
That wasn't much of a surprise to left wing Roope Hintz, a second-round pick (No. 49) in 2015 who was Heiskanen's teammate last season with HIFK.
