The Dallas Mavericks won their lone championship in 2011 with Rick Carlisle as head coach. Carlisle replaced Avery Johnson in 2008. He was on pace to lead them to the playoffs for the eighth time in 12 seasons before play was halted this season.
Carlisle was the head coach for the Detroit Pistons and Indiana Pacers before coming to Dallas. He led both teams to the Eastern Conference Finals. Carlisle is one of the best coaches in the NBA. That all makes no mention of his 11 seasons as assistant split between the Nets, Blazers, and Pacers.
