I would highly doubt any of the players on the team know who Kelsey Plumb is (or knew prior to her being mentioned alongside Caitlyn Clark). I just don’t know of any teenage boys plugged in to women’s sports. They might not know Maravich either, but I’d bet they’ve at least heard his name before. At the very least, he’s more relevant to them in their sport than Plum would be.
Which is not to say women don’t deserve recognition for their athletic accomplishments. They obviously do.
I don’t know who the all time goals leader is in soccer. That doesn’t take away from that dude’s accomplishment.
