I feel bad for the sons and can’t imagine trying to grow up in the shadow of such a loud-mouth, huge personality father. If he had step back, they might have had a chance to play basketball more or even do some modeling etc since they are nice looking kids. They seem like stage set piece in the dad’s wild show. It can’t be easy.
