Full backs were more useful in the 50's because they were frequently larger than defensive linemen, or BARELY smaller.
The league shifted to smaller shiftier HB's the bigger DL's got. The defensive linemen now are just too big and too athletic. Linebackers are as big as DL used to be back then and MUCH much faster.
