He was basically PJ axelsson with better point production for us, but for some reason he was hated.
But he's not PJ Axelsson, not even close. He may look like he's playing the same style as Axelsson with his stick and positioning, but he's never played the role Axelsson had in the NHL. Never.
PJ was in his time a top PK winger, and a top defensive winger tasked often with shutting down opposing players. Like Heinen, he could step-up in the event of injuries to play with two strong offensive players and not look awful because he was so smart.
And that is the issue with Heinen in the NHL. He can't carve out a role or niche on a team. These "jack-of-all-trades" types are useful players to have on a roster, but no one should be surprised when they go from a scoring line straight to the press box and back again.
What is Danton Heinen in the NHL?
Goal scorer? Nope
Playmaker? A little bit.
Grinder? No
Physical player? Not him.
PKer? Doesn't appear to be.
PP specialist? Yeah um no.
Defensive specialist? Not the way he's been used thus far.
Line Driver? Not a chance
Complimentary player on a scoring line? To a degree yes.
Part of a checking line? I don't think so.
So basically Heinen's best usage thus far IMO has been as a interim stop-gap complimentary winger with two stronger offensive players. So if you have a dynamic duo and you need a good complimentary winger for them, Heinen should be an option.
But if your top 2 lines are solidified, and your bottom lines consist of pluggers and grinders, I don't see a place for Heinen, because he's not going to be successful playing with lesser players than him IMO. His role on the 2019 cup finalist team was good for him. Kept him off the top 2 scoring lines, but played with two better offensive players in Coyle and MoJo. On a deep contending team he's a #9 NHL forward. As in I want my other 8 forwards on lines 1/2/3 to be better than him.
As a #9 Forward with two better linemates, give him some PK duty and sprinkle in a little bit of PP time, and he'd be in a position to succeed IMO.
