I have no doubt that in some ways college basketball is moving against coaches like Krzyzewski and towards those like Calipari (or even Rick Barnes). If college is just a quick pit stop on the way to the NBA, then you don't look for the best school or the best program, but rather the team that will showcase you to improve your draft status.
Nevertheless, the last paragraph is important:
"Krzyzewski has always been able to evolve with the changes in college basketball and remain at the top. He understands one-and-dones are part of the deal. But it's getting harder to maintain excellence in a college basketball world where academics and athletics aren't always on the same page."

The 2012 Olympics could well be Coach K's valedictory tour, but when he leaves Duke, I have no doubt that he would want to leave his successor with a strong and sustainable program. Coach K's best years were when he could recruit top players who would stay three or four years, with few exceptions (Brand, Avery, Maggette). Now commitments don't show up (Humphries, Livingston), top recruits seem less interested in Duke since college is only a pit stop (Patterson, Echenique, etc.), players leave quickly (McRoberts, Deng, King, etc.), and frankly a higher percentage of the prospects don't pan out.
Despite these four very serious problems, Duke basketball has recovered significantly in the last three years. We have a lot of talent coming back next year, albeit with some question marks, and the 2010 recruiting class looks very promising. So even though it's harder to maintain excellence and integrity, I don't expect Coach K to retire until he has Duke basketball back where he expects it to be, despite a contrary environment.
In a certain sense it's a case of plus ça change, plus c'est la même chose, as for many years coaches like John Wooden and Dean Smith, despite their imperfections, had to struggle against the Kentuckys of college basketball. So Coach K is simply continuing that tradition.
