"We think he's got some upside, some untapped potential," Flames director of amateur scouting Tod Button told CalgaryFlames.com after drafting Ruzicka.
"We think there's a lot of ceiling there to continue to improve and be more consistent with his play, as far as getting involved in the games offensively. He's a very conscientious player defensively but we think he's got more ability to do more offensively."
He did just that in 2017-18, scoring 36 goals and putting up 72 points in 63 games. He put 236 shots on net, leading all Sting skaters in the regular season. He earned more powerplay time and ended up scoring 11 goals and 28 points with the man advantage.
He also represented Slovakia at the 2018 IIHF World Junior Championship, playing in five games at the tournament.
"Overall, an unbelievable regular season," Conroy assessed. "And he had an opportunity to play at the World Juniors, which is great learning experience there, and then also in the playoffs.
"Now he knows he's got to take it to a whole other level. I thought he had a great regular season, working on the consistency, but then he also needs to be able to find that next level when the games ramp up and they mean more.
"And sometimes that takes time - just time. You're trying to learn about it, and when you're in those playoff runs it's not easy - everybody's going 100 miles an hour. It's a good experience to get in a few rounds, see what it takes to play a consistent game
"As good as he was, we need him to find one more level, one more gear in his play, and I know he can do that."
