The Ravens have re-signed big Musa Smith.  He had his best year in the NFL last season as he played in 12 games and carried the football 36 times for 153 yards (4.3 ypc) and he caught 22 passes for 135 yards (6.1 avg).  He should help the Ravens if he can stay healthy this season.  He also might get the ball more this season with Jamal Lewis out of the picture.
