I don't see that happening. The only reason the WNBA have eyeballs is because of CC. I think what is more likely is she would move into college coaching if she gets too banged up to play. A top 20 college women's BB coach can make over a $1M a year.
And they have their $#it together in college basketball.
The WNBA is political. And it's a weird clique and they don't want CC to be in it even though they're making money off her.
