I don't think you should ever call someone a "Generational _____" You could call anyone a "Generational something" if you think hard enough...In hockey or in regular life.
Chara is a "Generational Tall Hockey Player" Bergeron is a "Generation Defensive Forward" Marchand is a "Generational Rat"
Matthews might be the best goal scorer in the NHL, that's a fine argument to have.
First off, you could say "generational ____" for anything. Sure. But we're talking about goals. Not hits, puck retrievals, zone entries, slot passes, etc or any myriad of
measurable skills. Which brings us to what I bolded in your comment.
One of those is not like the other...which points to either a very bad faith attempt at engaging with me or a whole lot of ignorance.
A "generational defensive forward" could not only (theoretically
) be measured in a number of ways but it's a highly valued skill in a hockey player and is the kind of thing that will
likely get Bergeron a lot of attention when it comes to "all-time/HOF" considerations. Putting height and "rat" behavior next to that is nothing short of absurd.
To pit all of that against something as easily understandable, identifiable and valuable as
goals is uh...well like I said...a ton of bad faith or severe ignorance.
So let's transpose your disagreement here to a different sport, the NBA.
My theory: "Steph Curry is a 'generational 3-point shooter' because he is so far above and beyond his peers in 3-pt shooting."
Your rebuttal: "Only LeBron is 'generational' because being really good at 3-pointers is basically like being really fat or getting a lot of technicals."
The world: "3-pointers account for roughly 1/3 of an NBA team's points in any game and efficiency at 3 is often what makes or breaks a game between two teams. How the flying f@#$ is that remotely close to being fat or getting technicals?!?!"
Idk. I could just explain the value of goals in the NHL but seems like this is some kind of blind spot for you, so hopefully the NBA analogy illustrates how ridiculous you're being here.
