Generally speaking, young NBA players tend to fill larger roles as they mature, while gaining confidence and experience. Unfortunately for Robin Lopez, his career arc took the opposite path during four seasons with the Phoenix Suns. From Year 2 to Year 4, Lopez’s average in minutes per game dipped from 19.3 to 14.8 to 14.0. After starting 56 games in 2010-11, he did not start once in 2011-12. Amid what appeared to be a gradual regression, it became somewhat accepted around the league that the twin brother of Brooklyn Nets center Brook Lopez was more of an NBA backup than a first-stringer.
