First, both could be true: the infraction was minor AND Barker is part of the problem. I think there is evidence of this in her on-court actions this year. BUT, there is a bigger issue that I think you are pointing out. No matter what, she is not THE problem. In situations like this, there are almost always multiple causes. Which means there are multiple paths to improving and or avoiding the situation in the future. And I hope (and expect from what I've seen and heard from her) that Kim will evaluate her role, that of her staff, of other players, of player evaluation and what they are told during recruitment, and more during the off season. Because I'm 100% sure that Janiah has brought both good and bad to this team and is not, in any sense, THE problem.
