I actually like Turner over Wilson as I think Turner has a better motor than Wilson. When she played against us I thought she would kill us, UCLA, she had 14 pts and 16 rebs, did pretty well and as you say all her shots were close to the basket. Last year in the Elite 8, I watched Stanford leave her open away from the basket and take away her left in the first half and thus really negated her. Second half McCall forgot the game plan and let her get deep under the basket and she scored mostly left right near the basket.
The problem with those high % shots is that teams will leave her open away from the basket thus clogging the lanes that you talk about.
Turner, nor Wilson, are back to the basket players, who are usually responsible for "clogging the paint". Turner's so called easy looks are the result of an offense that is designed to provide them for her. In the game you mentioned against Stanford, Turner did resort to posting McCall up, but the post up often happened quickly (almost in transition) or by Turner cutting in from the free throw extended area. . If you watch clips, Turner is used in on-ball screens at the top of the key (pick and roll), she beats posts up the court, or she cuts in from outside the paint to get her at the rim shots. It's timing and athleticism.
PS- McCall is really underrated!
