If you play 33 minutes and take one shot it means you don’t want to shoot or maybe don’t even want to be there. The question is …why?
That is quite a leap. I attended the game, and I saw Evina pass up several 3-point shots where she was at least momentarily open. I also noticed that she was not hitting 3-point shots in the pregame warmup, and was visibly annoyed by that.
She was enthusiastically engaged in every other aspect of the game, e.g., rebounding, steals, and defense. Even her turnovers (other than those for traveling) were the result of overambitious passes on fast breaks. She did have one brain freeze when she failed to guard Morgan Maly after a 3-point attempt and allowed her to get the offensive rebound, but that was the only instance of "spacing out" that I saw.
I don't think there is any attitude or motivation problem other than a lack of shooting confidence. And it certainly is possible that she is one of the recent COVID cases, and may be a bit fatigued because of that.
I also think that PG is absolutely not her natural position -- she should be off the ball. That alone will reduce her turnovers by a lot. The biggest benefit of Nika's full return is that Evina should not have to play PG for very much longer.
