The Pittsburgh Steelers have very famously had incredible longevity in the head coach's office over the past 56 years.
Dating back to 1969, when Chuck Noll took over for Bill Austin, who went 11-28-3 in three seasons from 1966 to 1968, Pittsburgh has had just three coaches.
Noll walked the sidelines for 21 seasons, winning four Super Bowls, with just seven losing seasons in that time. Bill Cowher took over in 1992 and won a Super Bowl with just 3 losing campaigns in 15 NFL seasons.
Cowher retired after the 2006 season when Mike Tomlin took over. Tomlin is entering his 19th season for the Steelers with one Super Bowl under his watch, with an astonishing zero losing seasons.
Tomlin has coached to three .500 seasons of 8-8, which is impossible now that the league has moved to 17 games. Impossible until the NFL announces an 18-game regular season, which we hear is what the league hopes for soon.
Entering Season 19, Tomlin might have his biggest challenge ahead of him since ... last season. The team managed a 10-7 mark with no notable starting quarterback, and split the season between Justin Fields and Russell Wilson.
They're both gone now, and Tomlin and the Steelers are in trouble under center. Unless the Rodgers saga turns out as we're being told it will, with the four-time league MVP suiting up in the black and gold for the first week of the season.
Does Tomlin's streak hinge on the decision of Rodgers to play? Possibly.
