Yes, In 1973 the Steelers had the draft of the century, five players who ended up in the Hall of fame. Harris was drafted in 1972, so no wonder the Steelers ruled the NFL through the decade.
RIP, Franco Harris.
It was 1974 Draft, which was also a strike year. For some reason, the rookies were allowed to play during the strike. Jack Lambert, Mike Webster, Lynn Swann, John Stallworth, and Donnie Shell were in that class.
