Interestingly, Katz says

"Krzyzewski said that the plan is to have the team decided by the time it arrives at the Las Vegas training camp on June 30."

I could be wrong, but that would mean they would decide the team BEFORE the have the "tryouts." I guess they've seen them play, but in an earlier paragraph he talks about how players have gotten better since the last time they were together, which would seem to me that they would want to re-evaluate at least some of the players. Maybe I'm crazy, but it seems to me that deciding the team before they all get there and play for a bit seems weird...
