You know what they say about fantasy sports: You can't win your league in your first few rounds, but you can most certainly lose it.
In other words, virtually all of the players in the top 30 or 40 picks should theoretically give you relatively stable production, barring injury. Some (Kevin Durant) will be better than others (Rudy Gay), but you can't really go wrong in those first few rounds.
It's those middle rounds where you make or break your team by drafting breakout fantasy superstars in the making.
Here, I've gone through and pulled out the 25 most desirable sleepers in fantasy basketball for the 2012-13 NBA season, in reverse order. For me, a sleeper means two things: He's ranked outside of the Top 40 (according to a aggregate of ESPN, Yahoo! Sports/Rotowire and HOOPSWORLD preseason rankings) and I'd take him at least one round ahead of where he's being projected based on the aggregate ranking.
I tried to select five players of each position, but it's worth mentioning that many of these players are eligible for two (or three!) positions in fantasy basketball. Their positionality is noted in each title slide.
