Jack Sanborn

Jack Sanborn, a 25-year-old linebacker for the Chicago Bears, operates as the primary inside linebacker in a 4-3 zone-heavy scheme under Dennis Allen. He logged 78.0% of defensive snaps in 2025, recording 16 solo tackles and one TFL. Verdict’s dynasty score ranks him #72 among linebackers (34.0), while trade value sits at 833. Sanborn’s stable snap share and defensive production make him a low-upside but secure dynasty asset.

Sanborn’s 2025 production (16 solo tackles, 1 TFL) reflects a stable volume floor at 78.0% defensive snaps. He operates in a 4-3 scheme with zone-heavy Cover-3 shells, which prioritizes tackling and coverage over pass-rushing. No clear path to significantly increasing his sack total or pass-rushing opportunities exists within the current system.

Sanborn experienced a minor injury in Week 9 (2025), sitting out practice but returning for the next week. Prior to the injury, he practiced fully in Week 7, and the data shows no structural concerns or chronic injury issues. The linebacker’s moderate contact exposure (78.0% defensive snaps) reduces injury risk compared to higher-usage linebackers.

Sanborn’s defensive snap share remains stable at 78.0% in 2025, with no clear signs of regression or significant competition from other linebackers on the depth chart. The 4-3 zone-heavy scheme under Dennis Allen creates opportunities for tackling and coverage production, which Sanborn leverages effectively.

The 4-3 zone-heavy scheme under Dennis Allen suits Sanborn’s skill set as an inside linebacker. He excels in tackling and coverage duties, which the scheme prioritizes. No clear path to increasing his pass-rushing opportunities exists within the current system, and the stable defensive snap share provides a volume floor for his production.

Stable Sanborn’s stable defensive snap share (78.0% in 2025) and lack of variance in usage support the assessment. No clear trend towards rising or declining production exists based on available data.

Ceiling tracks near 2025’s 16-solo-tackle finish, given the stable defensive snap share and lack of clear upside opportunities. Floor follows the 2025 baseline, with regression below that line only possible through a significant injury or system change. A mid-season injury is the only realistic path to meaningful regression.
