Stability.

In sports it's something that doesn't come easily.

For the Steelers, it's a staple.

That became evident again today when Coach Mike Tomlin was signed to a one-year extension, keeping him through at least the 2021 season.

"I am pleased to announce we have extended Mike Tomlin's contract through the 2021 season," said Steelers President Art Rooney II. "Mike is one of the most successful head coaches in the National Football League, and we are confident in his leadership to continue to lead our team as we pursue our goal of winning another championship."

Tomlin, who was hired on January 22, 2007, will be entering his 13th season as the Steelers head coach. He is only the third coach the team has had since 1969, joining Chuck Noll and Bill Cowher on that exclusive list.

"I am very appreciative of this contract extension and opportunity and want to thank Art Rooney II and everyone in the organization for the support in my first 12 seasons," said Tomlin. "We have a goal of winning the organization's seventh Super Bowl championship, and I couldn't be more excited about this upcoming season."

Tomlin, 47, has guided the Steelers to two Super Bowl appearances. He became the youngest coach in NFL history to not only lead his team to the Super Bowl, but also win it when the Steelers defeated the Arizona Cardinals, 27-23, in Super Bowl XLIII.

"Mike's track record as far as I am concerned speaks for itself," said Rooney during an interview on SNR. "He is one of the best coaches in the league. We're just happy to have him on board. Happy he is on our side of the field.
