Bears Lock In Safety Overhaul: Thieneman, Jones Deals Signal Defensive Reset

The Bears announced agreements with both Dillon Thieneman (25th overall, safety) and Logan Jones (57th overall, center) on Friday, with Thieneman's fully guaranteed $19.51MM over four years setting the pace for what figures to be a swift draft-class signing cycle. Jones, the Rimington Trophy winner from Iowa, will pocket approximately $8.47MM with a substantial guaranteed chunk; both players are now locked in for the 2026 season and beyond.

The safety signing is the louder move. Thieneman enters Chicago to fill one half of a secondary that lost both starting safeties—Jaquan Brisker and Kevin Byard—to free agency after the 2025 campaign. The Bears partially backfilled that hole in March with former Seahawks cornerback Coby Bryant ($40MM, three years), but Thieneman's arrival completes the overhaul. At 6-foot, 201 pounds, Thieneman compiled 106 tackles and six interceptions as a Purdue freshman in 2023 (All-American honors), then posted 96 tackles and two picks in his lone Oregon season before entering the draft. The fact that he lasted until pick 25—with Ohio State's Caleb Downs, rated above him, going to Dallas at 11—suggests the market briefly undervalued him. Chicago didn't hesitate to correct that.

Jones, meanwhile, arrives as a successor to Drew Dalman, whose abrupt retirement created a sudden void at center. The Bears acquired Garrett Bradbury from New England in early March as a temporary solution, but Bradbury is positioned to hit free agency after 2026. Jones, a unanimous All-American and Rimington winner who started four years at Iowa, is positioned to takeover the middle by 2027 if the team opts to move on from Bradbury. That timeline matters: the Bears are not treating Jones as an immediate Day One starter, but rather as a foundational piece already under contract when the moment arrives.

From a defensive prop lens, Thieneman's role matters more immediately. The Bears secondary now operates with fresh salary-cap room devoted to improving coverage downfield, and the pairing of Thieneman and Bryant—both under 27 years old—should improve single-high safety metrics compared to the outgoing Brisker and Byard tandem. Look for Chicago's defensive efficiency (yards per play allowed, completion percentage in coverage) to tighten in the back half of games where they can afford to play two-safety shells. If the market has priced Bears defense props using last season's personnel numbers, the upgraded secondary creates edge opportunities in under-betting opponent passing volumes and receiver yardage totals in Week 1 matchups, particularly if Chicago faces a top-10 passing offense. The safety pairing is genuinely better positioned to create negative plays (interceptions, forced incompletions) than what exited, and that edge should persist across multiple weeks as Thieneman ramps into his NFL workload.

With five of six draft picks already inked (only third-round tight end Sam Roush remains unsigned), the Bears are moving with deliberate speed. The real test comes in September, when Thieneman's coverage ability and ball-hawking instincts face NFL-caliber quarterback play for the first time.
