Well its weird to me that its weird to you
Why do we all care so much about this team if hockey isn't about more than hockey? Why not support whoever has the best players of the moment, or change teams whenever we change cities? Would it matter whether it was the Pittsburgh Penguins or the Kansas City Penguins?
There's a sense of loyalty and belonging needed for a franchise to be a team. That history and culture matters. Without it fandom is a hollow exercise.
I don't think its at all weird to state that being a team legend should rest on buying into that culture and loyalty as much as talent and achievements. I get why people might disagree, but to me its a very rational way of looking at it.
And that doesn't mean we should expect all players to do so. On the contrary - the fact that we know they have a different outlook and careers to look after is part of what makes that sort of buy-in so special and precious.
And tbh, I think its always been clear that this was about more than hockey. Ultimately, if the question was "Did you spend a lot of time as a Pen being incredibly good at hockey", there wouldn't be a thread here. Everyone would answer yes. The questions start when we start asking what he meant to Pittsburgh Penguins fans and what it meant to him to be a Pen.
edit: p.s. Just had a look at the poll. 4 out of 5 fans here reckon he should be in. There may be a loud debate here, but in terms of numbers that's pretty clear cut by most standards.
