It is an irrelevant trophy. Like basically all awards are except for those that result in a Cup win (or at least in a Cup Finals appearance) or a blockbuster trade that restocks the organization.
Auston Matthews' Hart trophy is irrelevant if, for example, the Leafs never come close to a Cup with him as their main guy and he never gets traded for a ransom.
That said, I find it quite ridiculous that a fair number of posters "ridiculed" Kopitar for winning the "least of the trophies" in the past while I'm willing to bet a lot of them are losing their (your?) minds when watching players take absolutely boneheaded penalites, like Fiala does, while also losing against Oilers for the past 5 seasons who are at the very top of the league when it comes to using powerplay to their advantage.
Kopitar had 4 PIM in the previous regular season AND playoffs. 4. FOUR. I had to double check when I read that info on our local news outlet. And he did that while playing about 20 min/game against the teams' top lines in key FW defensive role. And that was for the second time in the past 3 years. That means he was basically available for ALL penalty kills this season which is also a huge boon (a good PK player is not that much of a boost if he's in the box for half of the PKs for example).
Of course it would be silly to have a team full of such players that never goon it up, BUT...having such a player as your cornerstone is IMO extremely valuable, and he's also a good example for younger, inexperienced players. I'd be willing to bet Fiala wouldn't take so many bad penalties had he "grown" under Kopitar's wing.
