That confidence has carried through to the start of this season.
"Once you know you belong, you're just more comfortable," Red Wings coach Jeff Blashill said. "He's gotta know he belongs, just through his play, both the end of last year through the world championships 'til now. Once you know you belong, boy, you're way more confident, you're more comfortable in your own skin. I think it just makes you a way better teammate, player, person. You can have way more success when you're confident."
In the first three games, Hronek has a goal and two assists.
"Yeah, I feel more comfortable this year," Hronek said. "Obviously I know more guys here now and I'm not that nervous like I was last year. Just everything, what you're supposed to expect from the league and everything. Now I know what it is a little bit and that just helps."
Another thing that has helped is Hronek is taking more shots. He is second on the team to Anthony Mantha in that category, 17-8.
"I was working on my shot during the summer," Hronek said. "He was talking at the end of the last year I'm supposed to shoot it more. I'm just trying to get it through and on net."
In Tuesday's 3-1 loss to the Anaheim Ducks, Hronek did not let the fact that he had hit the post and the crossbar deter him from shooting again.
The third time was the charm as he finally fired the puck in the net.
"I think he's definitely made a concerted effort to shoot," Blashill said. "I think part of it's where he's at on the power play on the off-flank there, it's a shooter's spot. He's really bought into that. I think he's worked at it. It looks harder to me but I can't say for sure. I don't know the velocity measurement necessarily but it definitely looks like it's coming off his stick hard. He's really had a weapon that way. Now I saw that last year, even when I watched him back in GR, he had at times a real weapon there of shooting the puck. He did that in the world championships and he's just carried it forward to this year."
Hronek has mostly played the point on the power play so he's still adjusting to the new spot.
"It's kind of (the) same but it's a little bit different," Hronek said. "I can shoot it more and not pass that much."
The development of Hronek and other young defensemen in the organization is incredibly important, especially with Kronwall's retirement.
"The growth of young defensemen in this organization is going to be critical for us to have success," Blashill said after Tuesday's morning skate. "I think from Hronek's standpoint, he's shown himself to be a weapon on the power play, he's had lots of responsibilities placed on him with the defensive pair that he's with and the fact that he's going to go up against the other teams' best players. So I think what's a successful year for him? Being able to handle that and us winning games. Be able to maintain that position in the lineup and us winning hockey games. That means he's doing a good job. Then also being effective on the power play and the penalty kill."
INJURY UPDATE: Center Frans Nielsen and defensemen Trevor Daley and Jonathan Ericsson did not practice Wednesday.
All three are on injured reserve.
"He's eligible to play Vancouver," Blashill said of Nielsen. "I think he'll be ready for that game."
The Wings are in Vancouver Oct. 15.
It sounds like Daley is in a similar situation to Nielsen.
