Well that's a major bummer. She'll probably still set the rebounds per game record (since games you don't play don't count against you), but A'ja is almost certainly going to get the new cumulative totals records. Hopefully, it doesn't affect her play beyond this year. It's a wrist injury, so it's going to hamper working on her shot, which, unfortunately for her, is one of the areas she needs to work on most.
I'm not a fan of her announcement post on Twitter, which includes a "me against the world" trope that is tired and just not true. She's been living a charmed life. Why does she have to act so aggrieved?
