Ah the old WNBA debate. ESPN is fully embedded into women's sports now and they have the rights to both the college women's game and the WNBA. The public needs to decide if it's really a thing, or just something ESPN puts on because they have the rights. And yes, you can twist numbers anyway you want. Of course the ratings were high this year, there were more women's college games on in more markets than ever before.
You will see a major push with the WNBA draft and Clark's first year in the league. And as much as they want to thank Clark for "lifting the league" up, they need to really thank ESPN. Now those who have at least followed sports from a distance knows the WNBA didn't start last year, or even 5 years ago. It's been around for over 20 years, and there has been some really good players in the league. Their major problem is and has always been interest. The NBA has supplemented this league since it's inception. I don't know that it ever changes. WNBA players want more money, better travel conditions, etc, but they can't even sustain themselves,that's why there are so few teams. At the college level through Title IX, men's and women's sports are directed to be equal. It's not that way with pro sports. It's well known that without the NBA's help, there would be on WNBA. Call it a subsidiary company of the NBA. Heck many former NBA players coach WNBA teams, including Bill Laimbeer and Michael Cooper.
So back to this thread's original question, I think a decade from now, Wembyana's impact will be much more felt than Clark. Clark can be a good solid WNBA player, but she's not going to dominate like she does at the college level.
