Think about it: If you grow up a college basketball fan, and have a son who's suddenly being recruited by everyone, don't YOU want to do official visits? To OSU? To MSU? To Kentucky or Duke?
I would. That would be a dream come true - and not just for my boy. Even if we both were already leaning to a school.
It's even fun for academic achievers. My son is no athlete, but scored near-perfect on the SAT. We settled on UC-Berkeley, but it was very fun visiting campuses and having people make their pitches. I'm proud of him, and it was fun to do together.
We fans get our identities wrapped up in our team loyalties, so we take it personally when someone considers other options. That's part of fandom, for good or ill.
But come on, a little perspective: I think most dads would LOVE this. And why not? Have fun, Smiths. Hope you join the UI hoops family, but even if not, enjoy it all. Life goes fast.
