You have zero idea what you are talking about. Zero. And how in the hell would leaving and not getting drafted be in his best interest? Are you serious? If he does what's best for him and his family he will return. They are not in any dire financial need, and coming back will be a wiser future investment for a bigger guaranteed contract.
The folks influencing the Bradleys are not on message boards --- they're unfortunately being influenced by leeches trying to turn a quick buck, and it's not a decision that should be affected by the likes of that rabble. So climb down off your self-righteous horse.
Oh, and BTW, yes, we would still be talking about weaknesses that need improving for next year, just like we already have been with other returning players. Pointing out that a player is not ready for the NBA is not attacking him.
