The other side of this coin - maybe there are some players who are so transcendent that it doesn't matter.
I bet AD would've been fine anywhere, too. All the guys in the conversation are or have the potential to be top 20ish all time players, but OTOH I suspect that bench guys, starters and borderline all stars (which is a more realistic aim for the vast majority of MCD AAs) might have better long-term prospects with a strong college coach who wants to see them succeed on top of winning, rather than a D league coach whose focus is more narrow.
Guess we'll see, though. I don't blame any kid who accepts, and I don't blame the NBA for trying to control their farm system.
