I think Diana Taurasi was born 20 years too early (and probably Cherryl Miller 40 years too early). I could see them being stars like Clark (or even bigger than her). They both had the skill and charisma.
And I think a big part of the Caitlin Clark star power is right place/right time/right look/right situation. The women's game has made a lot of progress, especially over the last several years (probably standing on the shoulders of UConn/Tennessee). And I think Clark's race/height/average looks all help too. She's a plain, white girl, that makes it easier for the masses to rally around, relate to, and envision themselves as. Many (but not all) of the women stars before her were taller, perhaps putting them in the "big men don't sell shoes" category (Leslie, Lobo, Parker, Stewart all 6'4" plus), darker (Swoops, Moore), less of a one woman show (Bird, Ionescu, anybody that played on the great teams like UConn, Tennessee).
She also has had good foes, in Angel Reese, UConn, South Carolina. Basic wrestling booking, everybody wants to see the baby face hero chase the title, take down Goliath.
To give some credit to Reese (and to re-emphasize the women's game is making progress), it's not all Clark (maybe just 90% Clark). A couple of WNBA teams, who have yet to face Clark at home, have seen a boost in home attendance (
at least according to his source). Still early (only a few home games each so far) but Dallas Wings up 1600, Chicago Sky up 1k, while all 6 teams who have hosted Clark at home have seen bumps, 2 of them (Aces +818 and Sun +657) are up less than what the Wings/Sky have done without Clark yet (4 other teams who have yet to face Clark have smaller changes +446, -129, -191, -640).
