3 longest-tenured coaches in Pittsburgh Steelers history

2. Mike Tomlin: 17 years (2007-present)

I don't know how many Pittsburgh Steelers fans would have predicted that Mike Tomlin's head coaching tenure would last longer than Bill Cowher's but here we are. Tomlin is entering his 17th season, and there's no apparent end in sight.

Most of Tomlin's post-season success came early in his coaching career. It was a tall task to ask a young head coach to fill the shoes of a Super Bowl champion and future Hall of Famer, but Tomlin won a Super Bowl of his own in just his second season as the Steelers head coach. Two years after that, the Steelers appeared in Super Bowl XLV against the Green Bay Packers but were defeated 31-25.

Tomlin has caught a lot of flack in recent years. Over the past 11 seasons, his team has only made it to the AFC Championship Game once. Pittsburgh is also on a six-year drought without a playoff win.

Still, Tomlin has never had a losing season in his NFL head coaching career. After becoming the second-longest tenured head coach in Steelers history, it's going to be hard for a future coach to surpass him on this list someday. Tomlin may be afforded the right to walk away on his own terms, and that may not happen until years down the line.
