Just because "lots of coaches" do it, doesn't mean it's okay. Those were the only examples you found? I think you missed a few. If you think it's okay for coaches to belittle kids and threaten their college careers, I feel sorry for your children.
Yes, that was all I found that offered "specifics" on the behavior. Most of the posts are just bald accusations calling someone a bully or saying someone is bullying. If there are some I missed, just point them out. But saying she's "threatening" college careers and "belittling" players aren't specific either. They are your characterizations of the words spoken by a coach to her players. What was actually said?
