The 2011 NBA draft was deep with role players and fringe starters. Unlike years past, this draft did not have a LeBron James, a Yao Ming or even a John Wall. Sure, Kyrie Irving and Derrick Williams may make an All-Star game or two, but no one is going to talk about the impact they had on their team, their city or even the league.
For most draft picks it's all about finding the right fit to excel. Most prospects at this point in the process are good enough to play in the NBA; they just need to find the right team. If you happen to be one of those unfortunate late first-round/early second-round prospects, the option to join a team that might need you right away may sound alluring but might lead to your ultimately shortened career.
Those players drafted in the late first round and then late second round often find themselves with more time to develop. There is no one expecting them to come in and change the team. Unless you happen to be Tim Duncan going to the Spurs, going early in the first round may not be all that great either.
We will likely see some guy bust out of the NBA after a year or two, but for some of these second-round picks, the right team found them, and their careers will be better for it.
