What is “Playoff Experience”?

I don't understand this concept of playoff experience the way everybody talks about it

So, so far throughout the playoffs, everybody keeps telling me about this magical concept of playoff experience

That's why they don't believe in the Thunder or they love the Warriors. And obviously, I'm not an idiot, right

Like on the surface level, I understand what people are getting at. Because like with anything in life, it's helpful to have done it before to try to do it again

But also having no playoff experience clearly didn't matter to Alper and Shang-Goon in game one

It didn't help a playoff vet like Fred Van Vliet from having a horrible game

If Quentin Post or Brandon Podzemski don't have any playoff experience, does that not matter

Is it only whether or not your stars have it? Like what even constitutes experience versus not

Is there such thing as bad experience? To me, what matters is just are you built for the moment

And some guys like Jalen Green in game one just look scared. So yeah, I'm taking him to score less than 18 and a half points on Dabble Fantasy

And if anything, I really think experience matters more for coaching than players

But all in all, I just want to know where's the line? What does it mean? Does it really matter as much as we think
