In 2017, the Steelers beat the Colts, Packers, Ravens, and Bengals with field goals in the final moments. Chris Boswell hit each of them. Had he missed, the Steelers could have gone 9-7.
In 2018, the Steelers and Chris Boswell weren't so lucky. Boswell was 13/20 on field goal attempts. He missed in OT against Cleveland in week one. He fell on his ass in Oakland in the waning moments. The Steelers missed the playoffs.
The Steelers had many problems. They turned the ball over too much and took the ball away too little.
If Chris Boswell can be the player he was in 2017, at least that's one less problem to worry about.
