Actually it did, my guy told me Diallo was a UConn lock, all but signed until we were really awful and Calipari snaked him.
As early as last season, long before the summer, when people were saying Diallo was a lock, people from Diallo's camp were saying, "No way, he is not." In fact, he was very interested in Kentucky already then. There was a disconnect somewhere. In fact, you'll find the threads here celebrating Diallo's silent commitment, which were quickly countered by Diallo's people.
What you have here is that Diallo told something to UConn people and they believed it, but it was never true. I've seen this play out the exact same way elsewhere.
