Oh yeah, fits Jagr to a T except for the several parts that don't describe Jagr - because he wasn't a power forward. I know that you started this unaware of what the term meant and I'm somewhat doubtful that you saw Jagr at his best, but at least look at the definition that you yourself provided. Was Jagr "equally capable of playing physically or scoring goals" - no, because he didn't play a particularly physical style even though he was very capable of scoring. Was he "likely to have high totals in both points and penalties" - no, only high point totals because he was an elite playmaker but not a power forward. Did he "dig the puck out of corners"? Not very often, not surprising as he wasn't a grinder or power forward, though once he had the puck he was extremely difficult to take the puck from. Did he "willingly engage in fights" - no, because while he was a very tough player in terms of taking punishment he was neither a fighter nor a power forward.
I do appreciate that you posted a definition which highlights some of the key areas that differentiate Jagr from actual power forwards he played against like Lindros, Neely, or Tkachuk though. The definition should still highlight the physical element more so than it does, but it's wikipedia and will probably be improved over time.
The point of posting that was to prove your assertion that there is a widely agreed upon definition of the term wrong - something you based your entire argument on initially.
And yes, he fits the he description pretty well, minus the fighting and penalties, like I said. No player will “check all the boxes” of that description perfectly. If that’s the standard you are holding to for a power forward, then there likely has never been one. Jagr fits most of the description provided.
Jagr using his size, strength, and physicality to drive the net, get to scoring areas, make plays, and protect the puck is one way of “playing physical”, whether you like it or not, and I think nearly everyone would agree. “Playing physical” does not strictly mean hitting, despite you wanting to frame it that way.
It’s funny how you selectively mentioned the parts of the description that best fit your narrative, and even then you aren’t even being truthful. I can do it the opposite way, without minimizing and trying to be disingenuous:
Was he big and strong? Yes.
Equally capable of playing physical and scoring goals? He scored a lot of goals and his game was based around using physical attributes to protect the puck and make plays, so yes.
Is he physically large? Yes.
Did he possess the toughness to dig the puck out of the corners? He would do so occasionally, if not regularly, so yes.
Did he possess offensive instincts, have mobility, and puck-handling skills? Yes.
Was he difficult to knock off the puck, or push away from the front of the goal? Absolutely, yes.
Did he possess both physical size and offensive ability? Again, yes.
Jagr fits the description better than the vast majority of players; I have just objectively proven that. You don’t like it? Too bad. You’ve lost, move on now.
