McClain is a former 4th round pick of the Ravens and a two-time Pro Bowler (2008-09).
After Steve Breaston signing this is definitely the best move the Chiefs have made all offseason. McClain is a gamer who can not only block, but can also catch and run with the football. He racked up 902 yards in 2008 but has recently seen his opportunity to touch the football diminished by the arrival of Ray Rice.
Aaron Wilson of Scout.com is reporting McClain signed for a one year deal.
