Is a sleeper really a sleeper?

So I was doing some blog surfing about basketball and I somehow landed on one of my favorite blogs, Give Me the Rock (You guys should go check them out!). Their latest post was about fantasy basketball sleepers. They were wondering if there was really such thing as a sleeper. Well, here is my take on it.

I think that when people usually say "sleeper," they are referring to somebody that they think will perform over the previous years' numbers. For example, Kobe Bryant and Lebron James are in no way, shape, or form considered sleepers because every year, people expect them to produce the same numbers. On the other hand, nobody expected Hedo Turgulu to have the season that he did. Maybe some people guessed it, but nobody downright would have said, "Turgulu is definately gonna have a great year."

This is what constitutes a sleeper. In this way, another term that is synonymous with sleeper is breakout candidate. So i guess in some ways, GMTR is right. There really isnt any such thing as a sleeper.
