She is not a leader, nor ever will be. It is just not in her DNA.
She also struggles if she is the "go-to" player. She does much better when she can play her role at a high level.
It reminds me of KAT on the Timberwolves. He is thriving being one of the main cogs, but not THE main cog that makes all the other cogs go. He was never comfortable with it and it showed. Now ANT on the other hand, he wants to be The Cog, and it also shows.
As for her Olympic aspirations, this will be a problem. Not only do you need to be able to play your role at a high level, you also have to be able to make the people around you better, too, because there are significantly fewer substitutions. She has clearly demonstrated she cannot do the latter, or at least has no desire to do the latter, if last season was any indication.
