Even Mittelstadt's unique season in 2016-17, in which he chose to return to Eden Prairie for his senior season bookended by stints with Green Bay, impressed Botterill.
"It's someone who's strong with their own convictions," Botterill said. "Yeah, he made a bold choice to go back but he also found a way to also be at Green Bay at the start of the season and at the end of the season.
"You can tell he's certainly passionate, he's certainly competitive in whatever sports he likes to play in. It certainly came across not only at the combine but at all the other interviews and interactions."
Botterill was asked how far off Mittelstadt, who is committed to the University of Minnesota for next season, might be from playing in the NHL, and he left the subject open.
"I remember when we sat down with Matt Murray talking about maybe after three years you're going to be maybe in a position to play in the National Hockey League, and now after three years pro he has two Stanley Cups," Botterill said.
"I think it's a situation where, yeah, going to Minnesota, it's a great program. You talk about strength training, it's a Big 10 school there, he's going to get that there. Plus you're going to play an up-tempo style ... I think it's a great spot for him and a great fit. We'll see how his development goes."
