The 34 offensive linemen drafted in 1974 weighed, on average, 255 pounds. By 1999, the 34 drafted offensive linemen weighed an average of 317 pounds, a 62-pound, 24 percent increase. During the same span, rookie defensive linemen gained 34 pounds, tight ends gained 33 pounds, and linebackers gained 19 pounds.
So a 317 lb lineman in 1999 isn't stronger than a 255 LB lineman in 1974?
