JuJu could very well break the scoring record (though I doubt it), but IMO it still wouldn't put her in the same league as Caitlin as a b-ball player.
Clark is not a generational player because she scores a lot of points - she's a generational player because of her all-around game, her vision, her IQ, and her ability to dominate even when she's the complete focus of the opponent.
Not taking anything away from Watkins, but I'll be interested when I see anyone come close to the combination of points, rebounds, assists and steals.
