Since we are talking about the next Olympics already, there are gonna be a lot of open spots on that 2028 Olympic team. I'd say the only spots I'm confident are returning (outside of injury at the wrong time) are A'ja (young and just peaking now), Sabrina (young and just peaking now), Phee (Young and just peaking now). Gray, Taurasi, BG and AT i think will definitely be done with either basketball or USA basketball by the time 2028 rolls around.
That leaves Jewel, KP, Jackie, Stewie, and Copper competing with the new blood for an Olympic return. Of that group I only really see Stewie and MAYBE Jackie being in strong consideration for a spot, just based on age and performance trajectory. That will leave minimum 7 spots open for all the new talent but up to 9 new players could be on that 2028 team depending on how things go.
My hottake unpopular opinion is I don't think Reese will be on that 2028 team. Not because I don't think she is great right now or has the potential but because I think she showed last year she has a tough time focusing in the offseason without the structure and discipline of the season. I'm not surprised she is doing so well her first season in the league because she jumped right in after college but I have more questions around how she will return for year 2. And then year 3 etc etc. But we will see!
