The Golden State Warriors kept Kevin Knox around just long enough for fans to believe he was the missing piece. While things didn't work out in The Bay, now he has a chance to pursue his NBA dream once again.
There are two versions of NBA draft busts. One version enters the league looking like a can't-miss prospect, and through some combinations of injuries and ineptitude prove themselves not to be an NBA player. That is probably the right label to apply to James Wiseman, for example.
The other kind enters the league believing themselves to be a future star, then reality sets in and they have to find another path to relevance.
