Note that PBS' page says that he has four kids, and I think that PBJ is the oldest. So wanting to play near his family, including younger siblings, could also factor into this decision. Obviously, if this is a really important factor, he could have also put schools like Wisconsin or Marquette on the list, but just throwing it out there, but in some ways that would also be even more of a slap in the face to his dad to say "I wanted to stay near home, but my dad wasn't good enough."
Every father-son relationship is very different. I know some dads who love coaching their kid. And I know some who would never do it. I coached my son in kindergarten soccer, loved the experience, and decided it didn't work for us going forward.
