Hronek was selected by the Red Wings with the 53rd overall pick in the 2016 NHL Draft, and he made his NHL debut on Opening Night in 2018. He played 46 games his rookie season, earning 23 points on five goals and 18 assists, and earned a full-time role last season, playing all but six of Detroit's games, earning 31 points.
At just 22 years old, Hronek led Red Wings skaters in ice time last season and played in all situations.
Red Wings coach Jeff Blashill said after Hronek's summer in Europe, the defenseman looked even better and hungrier coming into training camp this season.
"Fil is a tremendous competitor. He's a good hockey player, does a lot of things good," Blashill said during camp. "He's been really, really good, he's really competed hard. He looks like he's on top of his game."
Blashill has been right about Hronek's immense improvement through 18 games this season, as he's tied for the team lead in points (9), leads all skaters in average ice time by more than three minutes (23:59) and leads the club in power-play assists (3). Hronek has also been durable as one of only six Red Wings to play in every game this season.
Blashill said Hronek is a student of the game and is the type of player you have to drag off the ice.
"He's going to try to fight to be on the ice as much as he can," the Wings' coach said. "He's going to go out and play as well as possible, and he wants to play all night. That's the way he's wired, and you love that about him."
Like Hronek, Zadina was also loaned to the Czech Extraliga this past summer, where he earned 14 points on eight goals and six assists in 17 games for HC Ocelari Trinec.
Zadina was selected sixth overall in the 2018 NHL Draft and has shown flashes of brilliance in his sporadic time with the Red Wings. The 21-year-old had several highlight-reel goals last season and earned .53 points per game, which was good for fifth-most on the team.
"I want to be better all over the ice," Zadina said during training camp. "I've worked on probably everything I could this summer because it was a long summer. I've put on some muscle and put on some weight. I believe in the offensive zone and around the net, I'm stronger and I can find the pucks and create the chances for my teammates."
