Dalman joins the Bears after spending his first four NFL seasons with the Falcons. Selected by Atlanta in the fourth round of the 2021 draft out of Stanford, he became a regular starter in his second season and has developed into one of the league's best centers.
The Bears acquired Thuney from the Chiefs in exchange for a 2026 fourth-round pick and Jackson from the Rams for a 2025 sixth-round choice.
Thuney has played nine NFL seasons with the Patriots (2016-20) and Chiefs (2021-24). He has won four Super Bowls—two with New England and two with Kansas City—has been named to the last three Pro Bowls and was chosen first-team All-Pro in 2023 and 2024.
Jackson has started 61 games in five seasons with the Lions (2020-23) and Rams (2024), earning a Pro Bowl invitation with Detroit in 2021 in Johnson's first of three seasons as Lions offensive coordinator.
With three new starters, the offensive line will begin building on-field cohesiveness when the Bears begin practicing in May.
"As an offensive line, you want to be a unit, see the game the same way, through the same set of eyes," Thuney said. "It starts early. It starts in OTAs and getting in the film room together and seeing the film together, seeing how we see things, then getting on the field and playing next to each other; seeing how we fit, how we communicate. A lot goes into it, but I think this group can be really good and \[I'm\] excited to meet all the guys and get going."
Thuney is just as eager to begin the assimilation process.
"The challenge is just how much work you can put in, how much studying you can do, how much preparation," he said. "All the things that are in our control. I feel like that makes it really exciting and something that we can just work at every day and will improve over time."
