This season, Hronek split the year between Detroit and Grand Rapids, recording a combined 12 goals and 35 assists for 47 points in 77 games.
Jiri Fischer, the director of player evaluation for the Red Wings and general manager for last year's Czech national team, said the biggest improvement from him has been his ability to impact the game.
"Last year, he was a young defenseman that wanted to make things happen and this year he is a defenseman that's making things happen," he said of the 6-foot, 170-pound blueliner. "Plus, he's much more confident. He's got more swagger and is more in control than he was last year and all that leads to more ice time and getting more pucks from his teammates, which leads to more offensive opportunities."
Hronek said that after last year's world championship, he realized there was a lot for him to work on.
"You're playing some of the best players in the world and you see that you have so many things to work on. It's up to you to do it," he said. "Last summer, I wanted to improve everything, but especially my defensive game and making better decisions. I needed to be better mentally and use my instincts more. Not think too much and just play hockey. I also wanted to play the same all the time."
Fischer said he also saw a shift in Hronek's mindset that helped him find more success this past season.
"At the start of last year, he was asking himself why he wasn't playing more, but once he stopped looking at everyone else and started looking at himself, his mindset changed and he focused on getting better," he explained. "He went from being a healthy scratch to start the season to the No. 1 defenseman in the American League by the end of the season and this year he got called up and spent a lot of time in Detroit when the opportunity opened up because of injuries.
"All of the work he put into his defensive game and getting stronger and making better passes paid off," Fischer continued. "I hope he takes another step this next year and really becomes a defenseman that everybody wants to have on their team."
While he plans to work just as hard this summer in hopes of earning a full-time roster spot in Detroit this fall, for now, Hronek is quick to remind you that his season isn't over.
He's focused on doing whatever he can to help his national team win a medal at the world championship.
