Contrary to popular belief the Dallas Cowboys did not begin 22 years ago. We have not selected an Offensive Lineman in the first round in 30 years. In 51 years we have only selected 4. Scott Appleton in 1964 (never played for Dallas, singed with the AFL), John Niland in 1966, Robert Shaw in 1979, and Howard Richards in 1981.
By applying the logic only to Jerry's 22 years you must then assume we are taking a DL because we have done that 6 times since Jerry has been here. 8 if you count 2 guys who were moved to OLB in the 3-4, Ware and Spencer.
