9. Jack Ham, 1974
It's hard to come up with a list of the ten best single-seasons by a Pittsburgh Steelers player and not include Jack Ham -- one of the greatest players to ever suit up for this team. The problem is narrowing down the season in which he should make the list.
For as phenomenal as he was, Ham never earned Defensive Player of the Year honors, and the approximate value of his best NFL season ranks just 18th among Steelers in Pittsburgh's history. However, that certainly doesn't mean he's not deserving of cracking the list.
Ham made his mark from the gate and recorded a 7-interception season by year two. He was a First-Team All-Pro player every year from 1974 to 1979 and finished second in DPOY voting in 1978. I have the legendary linebacker making this list for his incredible 1974 season. His 5 interceptions in 14 games helped the Steelers to a miraculous season.
Ham added two more picks in the playoffs and was an integral part of helping the Pittsburgh Steelers to a Super Bowl win. Realistically, there are about six seasons we could have picked from, but the Hall of Fame linebacker certainly deserves recognition for his 1974 season.
