That means we get to see top college football stars remain in school at least three years.
In the NBA, players only have to be out of high school for a year. They also have to turn 19 during the calendar year of the draft, but that hardly comes into play.
Essentially, the top college basketball stars must go to school for a semester and a half, play one season, and then wave goodbye.
The one-and-done system means a great player such as Duke's Jabari Parker, who scored 23 in a win over UCLA on Thursday night, is leaving school the second the last ball is bounced in the Blue Devils' final game of the year.
The rule isn't fair to the players, because if they're good enough after graduating from high school, they should turn pro and forget college.
The rule isn't fair to fans, either, because the one-and-done players give the game a mercenary feel. And if your team isn't good enough to get a guy who isn't at least a threat to leave after a year, you probably aren't good enough to be all that interesting in the first place.
