A rookie in the NBA has many growing pains. From rookie hazing, the coach being extra hard on you, lack of quality playing time to opposing teams focusing on your lack of pro-level experience.
Yes being a rookie in the NBA is difficult and nothing proved this more than Kings' Ray McCallum recent stint at trying to defend Sixers' Tony Wroten.
During the first quarter of the Kings-Sixers game, the rook had his ankles torn to bits by Wroten. I mean it was just plain nasty!
