The Baltimore Ravens agreed to a four-year contract with third-round rookie running back Bernard Pierce according to Aaron Wilson of the Carroll County Times. The Ravens traded their third-round draft pick, 91st overall, and a fifth-round pick, 164th overall, to theAtlanta Falcons to move up seven spots to obtain their likely primary backup to Pro Bowl running back Ray Rice. Although Pierce will have to compete with Anthony Allen and Damien Berry, the ultra-productive 6-foot, 218-pounder immediately becomes the frontrunner to win the job and provide a physical presence behind the Ravens' franchise player. Pierce rushed for 3,570 career yards and 53 touchdowns, gaining 1,481 yards and scoring 21 touchdowns last season. Source: The Redzone
