He coached at Bowie for ten years then moved to Western Texas Junior College for three seasons, posting a record there of 101-13.

Richardson's frenetic, up-tempo system was new to Arkansas, and many fans questioned his coaching style after finishing 12-16 his first season.

His teams typically played an up-tempo game with intense pressure defense - a style that was known as "40 Minutes of Hell."

In 2012, his coaching philosophy was featured in the documentary "40 Minutes of Hell" on ESPN as part of the network's SEC Storied series.

Richardson is also among an elite group including Roy Williams, Denny Crum, Jim Boeheim, John Calipari and Tubby Smith as the only head coaches to win 365 games in 15 seasons or fewer.

His most controversial statement occurred in a post-game press conference in February 2002, when he spoke out against the athletic administration at the University of Arkansas.

He claimed that he was being mistreated because of his race, and challenged Athletic Director Frank Broyles to ruffle feathers by declaring, "If they go ahead and pay me my money, they can take my job tomorrow.

Richardson's former long-time assistant, Mike Anderson, was hired as Arkansas' head coach in March 2011.

[10] From 2005 to 2007, Richardson, (who speaks fluent Spanish) served as the head coach of the Panama national team.

In the middle of 2009, Richardson was named as head coach and general manager of a prospective WNBA expansion team in Tulsa.

While it seemed unusual to hire a coach before securing an actual berth in the league, the investors behind the expansion effort claimed this proved they were serious about wanting a team.

His first season ended before it began when key players who had led the Shock to three WNBA titles opted, for various reasons, not to make the move to Tulsa.

This forced Richardson to try to build the team around disgraced Olympic track star Marion Jones, who hadn't played a meaningful basketball game since her college days 13 years earlier.
