There were rumblings about this awhile back with something his father had said. Now it appears it is happening.
Williams is leaving Duke for family medical reasons and will attempt to transfer near his home in Memphis, TN. This is not unlike what former Tar Heel Alex Stepheson did at the end of last season. Like Stepheson, Williams will attempt to get a waiver so he can play right away instead of waiting a year as is customary for transfers. Stepheson had his request denied.
Regardless of rivarly you hope and pray things work out for Williams.
