According to the article, it sounds like those go to the team and owners, not the players. WNBA players don't even get a dime when someone buys their jersey.
Sure if she's doing a team endorsement deal as a part of her contact that goes to the WNBA, but if Vuori or State farm or whoever just sign Caitlin Clark to a deal to appear as Caitlin Clark the WNBA doesn't just take a cut of that.
Yeah, I saw an argument about considering not only what they're paying the athletes but also what those athletes are bringing in as far as advertisments, ticket sales, merch, etc. I can't find the video but I remember it clearly because it hadn't occurred to me before then. I'll look for it to make sure I'm not making any part of it up, but the numbers were ridiculous as far as how much money was being made from male leagues compared to female leagues.
