Cole Bishop's Knee Scope Won't Derail Buffalo's Safety Overhaul

Cole Bishop underwent a left knee arthroscopy in the offseason and has been held out of practice reps during Buffalo's spring work, but the 23-year-old safety expects to be available when training camp opens in July. Per ESPN's Alaina Getzenberg, the procedure was routine—a scope to clean up inflammation—and carries no red flags heading into Year 3 of his contract.

Bishop's 2025 season justified the Bills' decision to hand him the starting job after a pedestrian rookie campaign. He logged 91.14% of defensive snaps, the highest snap share on the defense, and recorded 85 tackles, seven passes defensed, and three interceptions while surrendering a 65.6 passer rating on 43 targets. That 65.6 mark represents a stark improvement over his 127.4 rating in 2024, and his missed tackle rate dropped from 11.1% to 6.6%. Pro Football Focus upgraded him from an 92nd-ranked qualifier in Year 1 to 41st among 91 safeties in Year 2—a tangible leap that reflects both better instincts and improved tackling discipline.

The knee procedure doesn't alter Buffalo's safety architecture heading into July. The Bills retained Damar Hamlin, signed C.J. Gardner-Johnson and Geno Stone in free agency, and drafted Jalon Kilgore in the fifth round. Gardner-Johnson will start alongside Bishop, with Hamlin and Stone competing for the third-safety role. Jordan Poyer—who posted just 43.58% snap share in 2025—has left the organization. The new defensive coordinator, Jim Leonhard (a former safety), is installing a scheme built for Ball-hawking and communication, which suits Bishop's trajectory. His timing matters: Bishop's absence from spring drills means he'll compress an entire offseason learning curve into July and August.

For prop bettors, Bishop's July return is anchored to one mechanic—snap percentage stability. He captured 91.14% of snaps in 2025 because the Bills viewed him as the scheme's anchor and the secondary's communication hub. Leonhard's system typically leans on the center safety as a quarterback-adjacent voice, which elevates playing time for a capable starter. Bishop's tackles and interception rates are durable; his tackling efficiency suggests he'll avoid the injury-prone label that sometimes doomed earlier-draft safeties. The real bet lies in his tackle total (he averaged 4.5 per game over 19 games in 2025) and his pass deflection floor. If Gardner-Johnson anchors the box as advertised, Bishop's high snap share persists, and his tackle average should hold steady or climb slightly.

One caveat: a scope typically indicates cartilage irritation or loose bodies, not structural damage. But "expected back for camp" is league-speak for "no structural setback." The Bills' decision to rebuild the safety room around Bishop—not around Hamlin or a veteran addition—tells you that front office views him as durable and scheme-essential. His July availability becomes the floor bet: if Bishop plays more than 85% of snaps again (near-certain given Leonhard's scheme requirements and Gardner-Johnson's role as a box safety), his tackle total becomes a lean under at anything higher than 82-85 for the season. The knee procedure is a blip, not a harbinger.
