The Baltimore Ravens signed veteran running back Ricky Williams on Monday.  This move makes sense for a couple of reasons.

First off, Ricky Williams isn't going to cost the Baltimore Ravens a ton of cash.  The Ravens signed the 1998 Heisman Trophy winner to a two-year deal worth $2.5 million.  Escalators in the contract could make the deal worth $4 million.  Williams should be a good complimentary running back behind Ray Rice.

Ricky Williams is 34 years old.  That's about the equivalent of an 85-year old man in running back years.  However, Williams was productive in his seven years with the Dolphins.  His standout season was in 2002 when he led the league in rushing with a career-high 1,853 yards.  Williams gained 673 yards and scored two touchdowns while teaming up with running back Ronnie Brown last season for Miami.  He has 9,565 career rushing yards and has a chance to become just the 26th member of the 10,000 rushing yards club.
