The praise he got later, was fraction of the criticism he got when he first started the season (and struggled)....It was just a massive win for him to even get a roster spot..Tocchet consistently speaks of his value to the roster.. I didnt read anybody saying he should play anywhere near a top 4 role.
He is basically the definition of an unsung hero, when you consider the long odds of him even making the team
That seems irrelevant to me, considering that his play early on warranted that criticism.
Personally, I don't think unsung hero refers to someone merely playing above expectations for their role/salary and being great value (I agree that he totally qualifies for that, on balance). By definition it refers to someone who hasn't been acknowledged for what they've done. Someone who's contribution has gone somewhat unnoticed and flown under the radar.
Juulsen's contribution has been fully acknowledged, and he got a little bit extra praise that was maybe a bit hyperbolic/not quite earned on top of that. Nothing he's done has actually flown under the radar.
To me unsung would be someone like Blueger in the first half of the year, who was critical to the team's success and was the best at playing a certain role but barely anyone gave a crap/everyone else got praised instead. Or maybe someone like Myers who was playing great but nobody really wanted to acknowledge it because of what we're used to from him and how often having any sort of hope in him turning a corner has ended up burning us. There was much more positivity surrounding Zadorov/Soucey/Juulsen and maybe even Cole earlier in the year, despite the fact that he's arguably been around as good as the best of those guys for most of the year.
Unfortunately, nobody who was legitimately unsung has really kept it up into the second half of the year.
I could see your argument if you were suggesting that the point of the actual award itself has little to do with the literal definition though, and that in practice, it's just to acknowledge value (similar to when MVP sometimes just goes to the best player rather than the literal most important one to their team).
