The Pittsburgh Steelers are giving Mike Tomlin a little more job security. The team is signing their longtime head coach to a one-year extension, according to Ian Rapoport of NFL Network.

As Rapoport points out, this means Tomlin is now locked up through the 2021 season. Tomlin wasn't entering the final year of his deal, so this is a gesture of goodwill from Pittsburgh's ownership. He wasn't going to be a lame-duck anyway, but this will ensure that Tomlin's contract situation doesn't become a distraction during the season.

Any kind of distraction is the last thing the Steelers need right now after their 2018 campaign was derailed by off-field drama. The Steelers missed the playoffs and finished second behind the Ravens in the AFC North, and Tomlin caught a lot of heat.

2019 is a very important year for the Steelers and Tomlin's future. The team needs to show they're still the top dog in the division, as the Ravens and Brown look to dethrone them once and for all. Tomlin needs to prove he's the coach of the future.

Tomlin has always been a polarizing figure, and his coaching style has come under a lot of scrutiny the past few seasons. Coaches have received extensions and then been fired many times before, so we probably shouldn't read too much into this new deal.

Tomlin will still likely be coaching for his job in 2019, and if he doesn't deliver, he could find himself replaced next season. This will be one of the most interesting seasons in recent Steelers history.
