Diop was one of the least important players to this legendary team. He played in a whopping 27 games all season and averaged 1 point per game when he played. It would be crazy to see where the Bobcats would have been without him. He probably helped them lose just
a few more games. All joking aside, he had a decently long NBA career despite averaging a mere 2 points per game over the course of his career. The 2011-12 season was his second to last, probably because he was 30 years old and no teams were interested in him. I guess after all of the losing, he decided to hang it up.
Diop retired in 2013, but he continued on with basketball as he became the assistant coach for the Texas Legends, an NBA D-League team. He works mostly in player development, because that's what the D-League is all about. The Legends are affiliated with the Mavericks which is a fitting home for Diop. He signed a six-year deal with the Mavericks during his career and he had his best seasons with them.
