From the moment he arrived at Kentucky as head coach in April 2009, John Calipari has been a master of one-and-done-era recruiting. Then, by 2013, Mike Krzyzewski had adopted that same approach wholeheartedly, with the result that Duke and Kentucky have now produced the top two recruiting classes nationally in each of the past five seasons.
For 349 other programs, however, recruiting is a far different matter. None of these "other" programs has been able to attain and hold onto the luxurious position of signing multiple one-and-done stars year in and year out. Programs such as Kansas, North Carolina and UCLA have done so at times; but at the end of the day, the duopoly maintained by the Blue Devils and the Wildcats is still standing.
