Eh, you're giving way too much credit to the Zenmaster. Indeed, part of the reason that nickname stuck is he used to masterfully use the media to play mindgames with the refs and opponents. He's an incredibly good coach. But, he's certainly not above taking petty shots. I mean -- this is a guy who wrote a book where he excoriated Kobe as "uncoachable," and just recently criticized Jim Buss (the brother of his fiance) as "a person that's vaulted into position through his inheritance." The Zenmaster has no problem being petty if you get on his bad side.
With regard to the NBA, while I think there may have been some truth to the NBA knock 10-15 years ago, it's been quite a long time since that's been the case. Frankly, Duke's current alums in the NBA today stack up very well against the current alums of any individual program in the NBA -- with the possible exception of UK that has recently churned out so many NBA guys. But, as others have mentioned, Brand, Boozer, Luol, and Kyrie have all made multiple all-star teams in the past decade, and -- health notwithstanding -- I expect we'll see Kyrie, Parker and Okafor all making quite a few all-star appearances in the years to come. And, to the extent we're focused on "expectations" -- which I view as the expectations going into the NBA -- I would argue that more Duke guys of late have exceeded expectations (see Mason & Miles Plumlee, Lance Thomas, and now Seth Curry) -- than have failed to live up to expectations (see Sheldon and Nolan).
