One of the reasons the Ravens have had success on the offensive line despite injuries is because they have two coaches at the position. Chris Foerster does most of the work with the first team while Greg Roman works extensively with the others. Few teams have two offensive line coaches. The Ravens signed Roman in March to work with the younger linemen. The Ravens had two offensive line coaches when they were in Cleveland, and it gave them a chance to develop starters like guard Wally Williams and tackle Orlando Brown. It usually takes three or four years to develop good offensive linemen. The Ravens pace is quicker.
