I don't understand this need to compare current players to previous players, especially as Geno remarked at his presser recently, we can't compare Crystal to Mo, because we only remember Mo as a senior. If we're going to compare Pheesa to Morgan (and I honestly do not see the resemblance except that they both play the 4 usually), then we have to imagine/remember Morgan in her 2nd year.
Pheesa has extraordinary athleticism and equally extraordinary instincts (which might not be different things). Her sense of the flow of the game, of players in the game, of the ball off the rim are all amazing. It's an usually high kinetic intelligence that goes with her outstanding physical gifts, at least IMHO.
