Much has changed for Baltimore Ravens quarterback Lamar Jackson since the last time that he squared off with the Pittsburgh Steelers.

Jackson's previous encounter with the Steelers came back in Week 13 of the 2021 season, when he threw one interception and fumbled once in a narrow 20-19 road defeat for Baltimore.

Jackson has since grown as both a passer and a rusher. Steelers outside linebacker T.J. Watt sees that Jackson's growing "comfort" with his weapons on offense is one reason why the two-time Pro Bowler has continued to elevate his game.

"I think it's comfort, comfort in the system, comfort with the guys," Watt said ahead of Week 5. "89 has always been a security blanket for him. Four now too. Just a bunch of other players that help him out. Just making quick decisions in the run game when it comes to mesh reads and the pass game."

Watt singled out both tight end Mark Andrews and rookie wideout Zay Flowers — two players who have blossomed as go-to targets for Jackson this season. Andrews currently leads the Ravens in touchdown catches this season with three, while Flowers ranks first on the team in a multitude of receiving stats, including receptions (29).

The Watt-led Steelers defense has had Jackson’s number as of late. For this trend to continue on Sunday when Pittsburgh hosts Baltimore, Watt believes that it will come down to several vital factors.

"It's about being decisive, doing your job, understanding who has what in the run game, obviously when there is a quarterback run element of it you can't try to do too much," Watt said.

"It's just tackling. I feel like every week I talk about tackling, but it's truly super important for us as defenders to get the guy on the ground early, so there are not those yards after contact."

Overall, Jackson holds a career 1-2 record as a starter against Pittsburgh.
