Kids flip in football all the time. Sometimes to the benefit of the Hogs. I don't recall anyone questioning those kids character. It's all about how smart they were and Arkansas is a better choice for their career, etc.
I get people don't like certain family members in this situation. However, it is hypocritical to be completely fine and excited when an out-of-state kid flips to the hogs and indignant when the reverse happens. BTW, if you can't see how family played a role in this, I can't help you. I wish people would lay off the kid though.
