I wrote a lot of about Wes Unseld's recruitment by UK on my Rupp page. Included in that is a number of mentions of his mother and father including in some newspaper articles from the time. Although it was known that travel in the deep South was a concern, I've never seen it stated directly his mother advised him against signing with UK, as you claimed.

So I'd appreciate seeing a reference to that if that's indeed true (which I frankly doubt).
Unfortunately, there's been a ton of inaccuracies and strange claims made about Unseld's recruitment over the years, by a number of people so it's a struggle to know and document what's factual and what's not.
