Let's think about this from Hronek's perspective.
You just got knocked out of the playoffs. Your production had slipped but you're likely not in the best space right now. Trying to process it all.
Some guy's question basically could be translated as: 'you've sucked lately, do you have an excuse for that?"
Hronek's right...if he knew why he was struggling he'd likely have adjusted. Sometimes you don't have the answers so pushing for one, despite having left you alone all year, is all about bad timing. Maybe you should have asked then not now? Because he's clearly not in the mood and not everyone deals with failure (which is what he's likely feeling) the same way. Dejection is obviously part of this and he's working through it. He smiled/tried. But don't get cocky and fire at him when he's not giving you what you want.
It's refreshing when players don't pretend everything's roses and sunshine or give canned answers to appease the masses. He's pissed off right now.
"Look we gave you your space" was the part of that conversation that was more of a challenge than anything constructive in my view. And, at this particular time, you'll likely get pushback from a guy who's unhappy (yes, clearly miserable) with the recent outcome of things. Surprise!?
