Why Tim Duncan's historic NBA career seemed to fly under the radar

Tim Duncan announced his retirement this week after 19 seasons in the NBA.

Duncan goes out as one of the most decorated players in NBA history. But despite having won five championship rings and two MVP trophies, Duncan was somewhat of an anonymous figure in a league that breeds superstars.

In addition, Duncan's success came in the shadows of some of the game's greats, and his titles came at some unlucky times.

Below we'll take a closer look at just how Duncan was so successful without all the accolades of lesser players.
