Safely stored in Arco, where nobody outside the FO will see it until after the draft, if ever.
It's considered very sensitive info, and will not be shared. That's what the Warriors did with their Jennings/Flynn workout session, too. A lot of teams are doing that sort of thing.
Rumor is that Flynn came out looking better than Jennings, but the rumor is all we have, and I'm doubtful about the reliability of any rumor supposedly coming out of Arco at draft time.
