Because it’s unacceptable to discuss it on this forum, now we need to e-mail the coach about it. Whatever. No one has said that neither she nor her coach are allowed to make the decision, I think the discussion is about whether or not she should be MVP, in light of the decision.
Now, I have no idea why this decision would be hers to make, but let’s assume it is. Then yes, she’s selfish, F her. In addition, F her coach for allowing it to be her decision. It’s clear she’s not qualified to make the right decision. So, in summary, F them both.
