Coach Rose is starting to sound like Yogi Berra: "This team is really just filled with so many young people who don’t know what they don’t know..."
I think that's a very unBerra saying -- it actuallly communicates what it is intended to communicate, with a twist of intentional irony. And he's been saying it for a very loing time. I don't think Yogi Berra's were intentional. And I don't think he repeated them. But as is so often the case, I don't really know what I don't know.
Follow-up: A quick google search (aren't they all?) attributes a variant of that quote to Noam Chomsky. As a tangent, Noam Chomsky firmly disputed that chimpanzees could use/acquire/create language. Back in the day, primate researchers trying to prove that they could (using, among other things, small blocks with signs on them) named one of their chimpanzees "Nim Chimpsky." That has stuck with me, for reasons I don't know. But I know I don't know them.
