I really believe it comes down to BYU versus Texas Tech.
The timing of the announcement makes me think it’s BYU. BYU basketball players can access training facilities on campus on the first of June. If BYU is his choice, he would likely make the announcement sooner rather than later so that he could be at those facilities ASAP and start working.
I believe that Texas Tech basketball players cannot access training facilities on their campus until mid June(see link). If TT is the choice, there would be no hurry for the announcement.
