Marion Barber RB CHI Jan 01 '78
Bears announced RB Marion Barber's retirement from football.
Barber isn't yet 29, but his body has begun to break down, particularly in the legs, and he's no longer an effective NFL runner. After a highly promising start to his career in Dallas, Barber averaged under 3.8 yards per carry in three of the past four seasons. The 2005 fourth-round pick was one of the NFL's most physical backs during the 2005-2007 campaigns, however, scoring 33 all-purpose touchdowns in his first three years. Ultimately, Barber was the personification of short shelf lives for power running backs in the NFL.
