Jack Ham remembers it well, still. It was in 1976, when the Steelers defense was so dominant that it forced rules changes, and the team had a game in Kansas City. So dominant were the defensive linemen on his side of the field - Joe Greene at left tackle and L.C. Greenwood at left end - that he, as the left outside linebacker, went through most of the entire first half without being touched. Picked on the 10th round by the Steelers from Arkansas AM&N, Greenwood was too slight to play for many teams, but Chuck Noll and line coach Dan Radakovich nurtured his athleticism. Recognized for the gold high-top cleats he wore, Greenwood was known as a big-game player. From 1973-75 he had 25.5 sacks; in Super Bowl IX he batted down three passes; and in Super Bowl X he sacked Roger Staubach three times. He is ranked second on the team's all-time sacks list with 73.5.
