Has to be within something like five years of their high school class and cannot sign an actual contract with an NBA team. Being drafted does not equal NBA contract. Njaji was a unique situation because, despite being drafted, he never signed NBA contact. They discuss this on the KSR Happy Hour episode today.Is playing in the NBA an actual reason why he cannot come back, or is that just a guess? Because before seeing that player drafted last year come back to college, I wouldn't have guessed you could do that either.
