No rookie enters the NBA fully ready to dominate through the rigors of an 82-game season.
Even the greats in the league who hit the ground running as rookies—LeBron James and Kevin Durant come to mind—continue to add to their skill set year after year.
There's a reason there's such a thing as a "rookie mistake," after all.
As players progress through their second and third years, that's when their overall skills should start coming into focus.
Here, I've highlighted 10 promising players in their second or third NBA seasons who all still stand to improve in (at least) one specific area.
Rookies were intentionally excluded from this list because it's just too early in their careers to know what's a trend and what's an early-career anomaly. Also excluded are young players who have already achieved superstar status, such as Kevin Love, Derrick Rose and Kevin Durant, because that's just nitpicking.
