11. Ahman Green, Houston Texans (2007):
After two under-the-radar years with Seattle to start his career, Green signed with the Green Bay Packers and truly turned it on to become one of the elite backs in the NFL, rushing for over 1,000 yards in six of his seven years with the team. That included a 1,883-yard, 15-touchdown 2003. Those numbers dwindled to 1,059 yards with five touchdowns in 2006, but Houston still signed him to a four-year, $23 million contract in 2007.
Green only played 14 games in two seasons with the Texans, rushing for 554 yards with only five scores – a large departure from his glory years with Green Bay. He returned to the Packers in 2009 and retired after playing eight games that year.
