All of this is per Katz yesterday. I doesn't matter what he says Monday, next week or even April 10. He could tell the new coach he is coming back then change his mind and go to the draft through April 29 (I think that's the day). There is nothing to stop him from waiting until April 29 to tell the NBA. He also can't work out for NBA teams so whatever evaluation he has now is probably all he is going to get because the NBA doesn't scout that much until the playoffs start.
