Kevin Durant. Carmelo Anthony. Russell Westbrook. John Wall. Michael Beasley. All five of these players made the decision, and probably the right one financially, to forgo multiple seasons of eligibility to enter the NBA Draft and become stars (aside from Beasley at the moment) at the next level after excelling at the collegiate level.
With the start of the "one and done's" beginning in 2007, more top players have left after one or two seasons rather than staying all four. Sure, there are still players like Nolan Smith who exhausted their eligibility before moving on to the pro game, but it has no longer become the norm that it was twenty years ago.
The players on this list only played one or two seasons of college, and are currently (or about to be) in the NBA and have had success in both college and the NBA. They are ordered from the year they entered the NBA Draft.
