I really like Royce White and I want the Celtics to take him, but...
There is 0 chance that Danny promised to pick anybody. He probably likes him and told him we would pick him if he falls to us. The way I see it, Royce White's agent was seeing that Royce wasn't doing great in the workouts. He mentioned some small injury in his twitter account even around the combine time.
His agent figures well we cancel the rest of the workouts, and instead of him lowering his stock, people start speculating he has a promise. His name is all over twitter and all of a sudden teams maybe looking to see if they missed something with this kid.
Maybe they'll ignore their concern for his off court issue because if a team like Boston thinks he's OK maybe it's not that bad... etc. Brilliant PR move by the kids agent because his name's never been more popular. Highly doubt Danny promised to pick a kid who didn't even work out with us.
