The man called upon to boost the Los Angeles Clippers to championship heights was once a point guard for four NBA teams, even appearing in an All-Star Game as a Hawk in 1988. Doc Rivers averaged 10 points and six assists over his 13-year career, appearing in the playoffs in 10 times.

Rivers retired after the '96 season, and after a brief stint broadcasting, became Orlando's head coach. After going just 273-312 after eight seasons with Orlando and some horrid Boston Celtics teams, Rivers had fans and media members calling for his firing. In 2006 ESPN The Magazine's Bill Simmons penned a column with the lede: "Doc Rivers stinks as an NBA head coach." As it turned out, a sudden influx of talent flipped the script.

After the formation of Boston's Big Three (Kevin Garnett, Ray Allen, and Paul Pierce) Rivers' teams won 371 and lost just 186. He's put his incredible leadership qualities on display, and has become the master of drawing up quick scores out of timeouts.

At 52, and with Chris Paul and a developing Blake Griffin in his arsenal with the Clips, Doc's future as an NBA leader seems to still be on the upswing.
