Grading the Chicago Bears’ Jack Sanborn and James Lynch Signings

The Chicago Bears took steps to add depth at some key positions on Wednesday with the signings of linebacker Jack Sanborn and defensive lineman James Lynch to one-year deals.

Neither transaction will dominate national coverage, but they matter inside a building trying to defend an NFC North championship.

Sanborn and Lynch are the kinds of signings that show up late in the regular season when depth gets tested, and roles start to shift.

Jack Sanborn Returns to a Familiar Role With the Bears

Sanborn’s return to the Bears just feels right.

He’s been in the building, understands the expectations, and has already proven he can step into meaningful snaps when needed. Whether that’s on defense or special teams, Ben Johnson and Dennis Allen will learn quickly that he's a player they can trust.

That matters more than it sounds.

The Bears reshaped their linebacker room this offseason, including adding Devin Bush, which changes the group's dynamic. But re-signing Sanborn gives them a steady, dependable option behind the starters.

Sanborn isn't flashy, and he doesn’t need to be. He entered the league as an undrafted rookie in 2022 and fought his way to a meaningful role with the Bears. He started 24 games during his first stint (three seasons) in Chicago and totaled 183 tackles.

He’s the kind of player who will give this team 100% effort, regardless of whatever his role becomes.

This is a strong depth move. No risk, clear role, and a valuable locker room guy.

James Lynch Adds Needed Depth Along the Bears' Defensive Line

The addition of Lynch fits where the Bears still had work to do.

Even after signing Neville Gallimore earlier in free agency, the defensive line needed more bodies.

Lynch gives them that.

A former fourth-round pick of the Minnesota Vikings, Lynch played the last two years with the Tennessee Titans. He saw action in every game over his two seasons with the Titans and has appeared in 71 games since entering the league in 2020.

He’s a high-effort interior defender who can play multiple spots along the defensive line. For Chicago, a player with Lynch's versatility adds another tool to Dennis Allen's toolbox.

Lynch will bring competition and depth to a group that struggled against the run in 2025.

Sure, there’s limited upside, but his role is clear. For a one-year deal, this is a smart, functional addition.

Grade: C+

Why These Moves Matter More Than They Look for the Chicago Bears

Not every signing is meant to change a team's trajectory. Some are meant to support it. And that's what Jack Sanborn and James Lynch do for the Bears.

Chicago has already made their bigger moves this offseason. At this stage, it’s about rounding out the roster, ensuring there are no obvious weak points when injuries hit or younger players need time to develop.

It also helps Ryan Poles' 2026 NFL Draft strategy. There's comfort in knowing there are reliable veterans he can rely on instead of being forced to reach for rookie fixes.

For a Bears team with legitimate Super Bowl aspirations heading into 2026, that kind of depth will pay dividends in January.
