After 11 seasons in the NFL, running back Ricky Williams has decided that he has had enough and he will be retiring. 

Ricky Williams has had an interesting career in the NFL.  If not for some poor decisions made early on, he may have been better than he was.  He announced Tuesday that he will be retiring.  At 34 years old, and 11 seasons in the book, Williams has put up some impressive numbers.

He one of just 26 running backs to rush for more than 10,000 yards (10,009 total).  He had 74 career touchdowns.  A former first round draft pick, he had five 1,000 yard seasons, and was great for both the New Orleans Saints and Miami Dolphins from 1999-2003.

In 2004 he briefly retired after he failed the league's substance policy.  He would have been suspended for four games for the 2004 season, but instead decided he would rather leave the game behind.  He couldn't leave for long as he returned to the Dolphins in 2005.  He played for the Toronto Argonauts in the CFL briefly in 2006, and returned back to the team where he will be most remembered, the Miami Dolphins.  He played there 2007-2010 before signing with the Baltimore Ravens for 2011.
