The deal with the kids is probably more to do with being able to live more of a rockstar type lifestyle with dad and everyone knowing who you are. Knox is living every kid that ages dream life right now. He's surrounded by superstar athletes that include him in everything. The daughter seems to like the smaller town Oxford life and all that affords her as far as popularity and groups of friends. In their position, most kids that age would want to be on TV weekly with their superstar dad. Can't really knock them for that. And with dads position, they are a private jet ride back to mom anytime they want.
