I agree with mostly everything you stated, with the exception that Cam Brink is more pro ready than Paige. Brink is definitely pro ready and I think her upside potential might be the highest of all as she is adding dimension to her game, particularly her outside shot. While Paige might be a question mark as to the physicality of the WNBA game, her game translates to any forum. There's literally nothing that she can't do on a basketball court.
As you pointed out, the other players have basically accomplished everything in their collegiate careers. While Clark has not won a NC, I don't think it's a likelihood this year either. She will have set a new NCAA scoring record, and if she stays, won't have Gabby Marshall or Kate Martin as teammates. Plus, it's hard to pass up being the #1 pick in the draft.
SC & UCLA are the frontrunners for the NC. If Cardoso wins, there's never a better time to go out on top. The same could apply to Angel Reese. It might behoove her to escape the media circus that comes playing for Kim Mulkey & LSU.
Selfishly, I would love to see Paige play another season at UConn. As Geno mentioned in an interview, Paige is basically still in her sophomore season when you consider the number of games she has played. She came to UConn to leave her imprint alongside the other greats of the program. Is she willing to depart not having won a title? I imagine that is one of many factors in her decision. UConn's chances this year have taken a hit, but what if they come close again but miss out? Would that impel her to give it one more try with a healthy & fully loaded roster? Time will tell.
Nine games into the season, Paige appears to be holding up well. However, if she opted for the draft, she's exposing herself to the rigors of potentially 80 games or more in a year's time period. That's a lot for any player, let alone one with a checkered health history and coming back from a serious injury. From a physical standpoint, as well as a nod to a long, healthy career, I feel she would be better served by returning and using the college offseason to recover and get physically stronger for the more demanding WNBA.
In 2025, teams would in scramble trying to land her as the number 1 pick.
