Even though I don't follow the WNBA or Womens basketball those 2 first names are well known. I just want to sell the domain names.
Okay, so how many other "first name" domains have you registered? Just this one? Gosh, what recent events could have caused someone, out of countless first names in the world, to focus on this one?
I'm not trying to be sarcastic, but missing the obvious context seems to be a common domainer blind spot.
Now, sure, I've defended plenty of domain disputes which involved principally a first name or a surname. Typically, those defenses have included arguments and evidence to the effect of "The Respondent has registered a lot of other similar names."
But if your argument is "I registered these names because Caitlin is just a first name" then the question is "There are a lot of first names. What other ones do you have (and when did you get them)?"
If you are found in a tree at night next to someone's bedroom window, saying, "Oh, I just like to climb trees" is not a complete explanation of what you were up to.
