What are the Chargers Getting with UDFA C Jacob Spomer?

The Los Angeles Chargers signed former Fresno State center Jacob Spomer as an undrafted free agent following the 2026 NFL Draft, adding competition to a position group the Bolts heavily addressed this offseason.

While they signed veteran Tyler Biadasz to a three-year, $30 million deal this offseason to replace recently retired Bradley Bozeman and selected Florida center Jake Slaughter with the 63rd pick in the second round of the 2026 NFL Draft, the Chargers continue adding help on the interior of the trenches with the signing of Spomer.

The 24-year-old Brentwood, California native spent all four seasons of his college career with the Bulldogs, earning First-team All-Mountain West honors in 2025 after allowing just eight total pressures on 437 pass-blocking snaps without surrendering a single sack. He also committed seven penalties across 863 total snaps while posting an 81.5 pass-blocking grade from Pro Football Focus.

During his junior season in 2024, Spomer recorded a career-high 85.4 overall grade from PFF, along with an 81.1 run-blocking grade and an 89.0 pass-blocking grade after allowing just one sack and three total pressures on 178 pass-blocking snaps following his return from a torn ACL suffered in 2023.

At Fresno State's Pro Day, Spomer measured in at six-foot-three and 290 pounds with 31 1/4-inch arms, 10 1/8-inch hands and a 76 1/4-inch wingspan. He ran a 5.14-second 40-yard dash with a 1.80-second 10-yard split, while also posting a 7.37-second three-cone drill, a 4.60-second shuttle, a 28-inch vertical jump, a nine-foot-five broad jump and 28 bench press reps at 225 pounds.

Spomer is an interesting prospect because, coming out of junior college in 2022, he was initially placed at left tackle before eventually moving inside, where he found the majority of his success.

He provides positional intelligence that should translate well into new Chargers offensive coordinator Mike McDaniel's system, particularly in identifying fronts and making pre-snap adjustments.

For the Chargers, Spomer could potentially develop into a valuable depth piece if he progresses as expected. With continued development, his athleticism, technical consistency and football intelligence give him a path to eventually compete for a starting role along the interior. His versatility could also increase his value on game days, especially if he proves capable of handling multiple spots across the offensive line throughout training camp and preseason action.

Spomer is an appealing practice squad candidate with long-term developmental upside for the organization as injuries have continued to dismantle the offensive line in recent years.
