Folks have known about Brittany since her college days, it is very rare to see a 7' woman.She plays in the WNBA. Very few people (relatively speaking) care about the WNBA and that fact alone made Griner not very well known.
The average casual sports fan knows the names of 10-12 current NBA players off the top of their head. They have some opinion on who’s the best currently and all time. Those same people probably can’t list 5 WNBA team names let alone players. BG is far more famous now than she ever was or would have been because of her play on the court. That has zero to do with her skin color or who she’s sleeping with. It’s because womens basketball is an inferior product to men‘s so if Im a basketball fan why would I watch the inferior league? An average D3 mens basketball team would wipe the floor with the WNBA all star team.
