Re: the FG%, your qualifications don't matter to the team, they're individual points. Kiah's choice of shots resulted in balls in the cylinder more frequently. I'll grant some veracity to the the TO point though, as Kiah passed much less than Steph. (But only some, since many of Steph's TO's were due to her propensity to dribble across the top of the key and get stolen or dribble off someone's foot.

)
Agree on Kiah's likely use -- given all the shooters on the team, her strength, athleticism, and mobility, it would be silly to pull her away from the basket much.
