In the '02-'03 season, Sidney Lowe was on the hot seat as head coach of the struggling Memphis Grizzlies, and after an eight-game losing streak and a toothpick incident, he was fired.

Warriors coach Montgomery had two 34-48 seasons, with GM Mullin wanting him fired. Don Nelson replaced him, leading the team to a playoff upset of the top-seeded Mavericks.

Iavaroni failed to lead a talented Memphis Grizzlies team in 2007, resulting in a poor start in '08-'09, leading to his firing. The team has since been mediocre but better off without him.
