It has been almost 200 days since the Pittsburgh Steelers’ season ended short of the playoffs when they were edged for the seventh spot in the AFC postseason derby.

After a season that ended on a four-game winning streak came to an abrupt finish, the work to prepare for the 2023 campaign began almost immediately.

In the ensuing months, the Steelers signed free agents, completed trades and conducted a draft. They went through organized team activities and minicamp — all to get to this point.

The start of training camp officially marks a new beginning for all 32 NFL teams, a chance to put all of that offseason work to the test.

For the Steelers, who report to Saint Vincent College on Wednesday and begin practice a day later, they will see whether they can improve on a 9-8 record and perhaps piece together a team capable of winning a playoff game for the first time since the 2016 season.

Many storylines will play out over the course of camp and the preseason. These are five worth watching for the Steelers:

1. Who’s left?

The left tackle competition is the most significant of any that will take place before the start of the regular season. Dan Moore has held the position for the past two years, but the Steelers traded up and took Broderick Jones with the No. 14 overall pick.

Jones won’t be second string forever. It’s just a matter of how quickly he develops and how comfortable the Steelers feel about having him protect Kenny Pickett’s blind side when he enters the lineup.

Moore took most of the first-team snaps during offseason workouts, although he also repped on the right side (perhaps to prepare for a potential switch). More will be known once the pads come out for the first time Aug. 1, and the left tackle candidates will have to fend off experienced pass rushers.

2. Where does Joey Porter Jr. fit?

Porter remaining on the draft board after the first day of the draft was a surprise. When the Steelers used the first pick of the second round to select him, it was not unexpected considering his bloodlines and the familiarity with his play.

Porter, known for his work as a press corner at Penn State, will have a chance to earn a starting spot in training camp. Veterans Patrick Peterson and Levi Wallace are the presumed starters, with Peterson working on the left side and Wallace on the right. But Porter has a chance to figure into the mix, particularly if Peterson moves into the slot on some passing downs. He also could unseat Wallace at right corner.

3. Tying up Tomlin

The last time the Steelers extended coach Mike Tomlin’s contract was April 2021. That extension tied Tomlin to the Steelers through 2024.

Historically, the Steelers have added time to Tomlin’s contract when he has two years remaining. And, the 2021 deal aside, such extensions have taken place at the outset of training camp. So don’t be surprised if the Steelers announce an extension Wednesday.

Working in Tomlin’s favor are the 16 consecutive non-losing seasons and .636 winning percentage. Weighing against him are those four consecutive playoff losses, starting with the 2016 AFC championship game.

4. Does anyone begin on PUP?

It’s not uncommon for at least one player to open training camp on the physically unable to perform list. Such news often is revealed after the conclusion of the run test on reporting day or the first day of actual practice.

The most likely candidate is inside linebacker Cole Holcomb, one of two starters signed at the position in free agency. Holcomb had foot surgery in December and was mostly a bystander during organized team activities and minicamp.

Holcomb said he will be ready for training camp, but general manager Omar Khan also has said the Steelers don’t want to rush his return.

Tight end Pat Freiermuth and wide receiver George Pickens were among the skill position players who missed minicamp with what were viewed as minor injuries. They were expected to be ready for training camp.

5. Getting the boot

When Pressley Harvin III won the punting job in 2021, he beat out veteran Jordan Berry for the job. Harvin enters his third training camp also having the disadvantage in experience.

With the April waiver claim of Braden Mann, a 2020 draft pick by the New York Jets, the Steelers will have two veterans competing for the job. Harvin has the advantage of a working relationship with long snapper Christian Kuntz and holding for kicker Chris Boswell. Mann, though, preceded Harvin as the Ray Guy winner, an award given to college football’s best punter.

Inconsistency has dogged Mann and Harvin during their NFL careers. Whichever punter is the most consistent in the preseason should determine which one gets the job in 2023.
